I really like the food and atmosphere. Employees are all good. The biggest issues is management cant seem to count! Ive been coming here for months and they are out of bagels by 9:30 10 am almost every time now. This is a bagel place and since they cant figure out how to keep stock. Ill be making my bagel sandwich at home. Plus the line is always long, they should let people know they are out of their main product on a daily basis. If you want a bagel sandwich cone early or dont bother.Wish they could figure out there stock issues and fix it! Silly!

Perfect location and gorgeous coffee/wine/beer shop. Chill here while you work or hang with friends. You won’t be disappointed. Top notch service too!

This is my go-to neighborhood place for coffee and bagels. Their lox bagel sandwich is amazing and affordable for what you get! On a nice day, I enjoy chilling on their huge patio. There have been a few service snafus - I find that ordering through the ChowNow app and then walking to pickup, I have no wait time. My one complaint is that several times that we have tried to get coffee in the late afternoon, we were told that they stopped serving coffee for the day. Even though their website advertises having drinks and coffee all day. Every coffee place in this area closes early, so I think they would be able to capitalize on this by having coffee til close. If this happens, I’ll increase my review to 5 stars!Updated 10/31/21: they have since updated their coffee service til 7pm which we appreciate!! It would be even better til close, but still a favorite neighborhood spot.

Great place that was new to us. If you like Leroys Bagels, I think they get them from there. Coffee is delicious and staff is friendly. Add this place to your daily routine. Just need to go get a drink here now.

Great place to hang out and work or meet with a friend. The staff is really friendly, great spacious patio area, TVs behind the bar, or nice couches for a more comfortable vibe. Coffee is not the best but there are plenty of other great options. If they stepped up the coffee game this place would be perfect!

The Radiator is a refreshing and modern update to the charming but barren Common Grounds that stood in its place the year before. The space is open and airy. The staff is welcoming and friendly. The furnishings are comfortable and inviting.I can’t wait to meet up with friends here or camp out for an afternoon with my laptop and a book. With space to run around and a few things for the kids to play on (not to mention the nearby playground down the street) I’m also adding this to my list of go-to spaces to entertain friends with little ones (two-legged and four-legged alike)

Just lovely!Attentive staff. Great coffee. Happy, comfy vibe.Going back for a wine evening.A marvelous place, as casual as home just a stroll away, but a fun change of venue!

This is the perfect place to have a coffee and a bagel and appreciate fall.

Wow super cool spot! A+ design and location. Very covid friendly. Food is outstanding and by far cheapest in neighborhood. Beer list is great combo of local and imports. Wine list presents amazing value. Definitely going to be a regular spot for us! Service is super friendly, already remembered my name!

Awesome place and ambiance. Only downfall is they dont serve liquor. But outside of that this place is great. NBA arcade game, cornhole, and TVs. Great place with friendly staff. I recommend it!

My favorite morning spot for coffee, bagels, and wifi and evening patio for drinks, food, and a vibe.In the morning, solid iced Americanos, bomb rosemary bagels, and the most affordable breakfast sandwiches you can find in the area (Im looking at you, Rosenbergs).For later in the day, amazing food options and beer and wine selections to go with them. When they’re posted on the patio, Split Lip Chicken has the best burger and hot chicken sandwich you can find in Denver. The hot chicken sandwich has the crunchiest exterior, cool slaw, and the right amount of heat. And the burger is exactly what I want it to be: potato bun, thinly sliced pickles, and juicy patty with the crispiest/craggiliest edges.

Fun vibe, pretty good coffee, but not quite the best in the area. Great place to work if you dont need a charger (limited spots if youre not down for sitting at the bar)

We stopped by for a bagel sandwich and coffee, which we enjoyed outside in their great patio area. They lost my sandwich ticket, but quickly made it when it was brought to their attention.

One of our favorite local spots, they have bagels from Leroys and they are top notch. Could not recommend the environment and quality of food more.

Not going to lie. I honestly came in crossing my fingers, just hoping it will be at least ok. Well I was wrong. It was good good! I have yet to try out 95% of the menu... So for now, Ill be back later.

Sadly I arrived too late for bagels on this visit but have enjoyed them for takeout on previous occasions. We tried two of the wraps which were good. Staff was friendly and helpful. Drinks were good. A little confused about the cocktail menu since they do not offer anything with hard liquor. Great beer list though!

Editing my review. I so wanted to like this coffee shop but man is the service slow. I timed it this last time. Placed my order (coffee and a bagel with pain cream cheese). Picked up my order on the counter 18 minutes later. They also pick favorites and will say bagels arent available only to give them to someone who arrives later. Which is fine, but I wish they would just say that instead of lie. Drip coffee of better than the espresso drinks. Leroys bagels are okay... Wish they had partnered with Rosenbergs.

This was such a great find! I just moved to the area and was looking for a solid place to chill for a couple of hours in the afternoon. The baristas were super friendly and made one of the best drinks I’ve had in a while (Iced Lavender Matcha Latte)! The inside was super cute and the music was very relaxing. The outdoor patio is ADORABLE. Very spread out and not too crowded which was great for COVID distancing. I will absolutely be coming back to try their bar menu, which looked incredibly diverse. SO happy to have found this place!

This place was adorable! The staff was super friendly and helpful. They serve really yummy breakfast bagels and burritos. Highly recommend

Great place but Ive been here 5 times and EVERY time theyve been out of bagels. I finally decided to ask about the issue and the person at the register just told me to expect that theyll run out of bagels most days...like, what?! Ordering more bagels and ending the day with some extras isnt going to kill your business, but consistently running out of food will.

Music was a little loud for working, but it was a great environment otherwise. Wifi was fast enough today Zoom voice calls but couldnt stream video group calls.

They didn’t have any of the sandwiches we want but oh my gosh we were not disappointed!! I ended up with an egg and cheese on sourdough bread and an earl grey tea, and my wife got a BLAT and a lavender matcha latte and we were in heaven! The staff were so nice, our food was out quickly and this little place was so so good. Gender neutral bathrooms which is always fantastic, definitely LGBTQ+ friendly!!

Nearly everytime they are out of bagels. They have improved service a little. Dont have to wait a half hour anymore. Im guessing they solved this by not allowing same day orders to go or online (which makes that service useless) and sending all calls to voicemail. Seems they patched the problem but didnt solve it. Its sad frankly.

The coffee is soooo much better than Starbucks and they serve great breakfast items too!

Great place for coffee with a friend, great food, plus on tap beer, and a great selection of wines. Big TVs and Great staff🙂

After coming here for months and ordering the same thing the baristas could never remember the order. Better service at Starbucks up the road. The order is the same yet every time we’re charged it’s a different price. Today was charged for large and they didn’t even have large cups so they just gave me a size down for the same large size. Absolute zero consistency’sToday was the last time I’ll ever go . Ordered. After ten minutes of cups sitting there and employees just talking to eachother did they start the drinks. Ridiculous service.

Great lighting and seating, a big pet friendly patio, also good wifi. If you want to get some work or reading done, its a great spot. Good coffee, wish their matcha was stronger but makes a good latte, and a small but good menu of sandwiches and bagels. Staff is very friendly and helpful.

This place is quaint I love the outdoor patio vibes. Great drinks as well!!!!

The Chagaccinos are divine. A great coffee spot in the morning with friendly staff and plenty of indoor and outdoor seating.

Decided to give this place a try and it did not disappoint! The food was delicious, we had jalapeño cheddar bagels one with lox and one with bacon and they were fantastic! The atmosphere inside is another plus, it makes you feel like you’re hanging out in your living room. Check this place out if you’ve never been!

I want to love this place but they need to improve big time. Their staff isnt friendly or even acknowledging about basic things such as how far theyre behind in making a drink or sandwhich. Ive given them 10 tries and every time they have several customers waiting upwards of 20+ minutes for a coffee or even longer for a sandwhich. You can see the frustration build on everyones face waiting for their order. It would be faster at a sit down restaurant. They are often out of their bagels. This message is hopefully to make management know there are 1. Missing money due to how slow they are making orders and 2. Letting others know dont come here if you expect a coffee quickly. It could be 25 minutes before you get it and they wont tell you that or even acknowledge you waited forever. Staff stinks but likely thats the managements fault.

Great patio and atmosphere. One of the better bagels in Denver. Beer, wine and coffee.

So bummed when Common Grounds left but Radiator has made it all ok. Couldnt be happier and we love the place: comfortable and fun space, stellar bagels and super great staff! Cant forget about the yummy drinks all around.

Love this new spot in the neighborhood and probably have been in a dozen times. My only complaint is that they run out of food too fast. They order their bagels from Leroys and local burritos elsewhere and should probably up the quantity. Also, only happened once, but I ordered a chai with oat milk and got real dairy instead - not a good mistake to make. I know they are still somewhat a start-up so they get a pass for now. I look forward to stopping in again soon.

Nice atmosphere. Good coffee and bagels

Good coffee and delicious light food. The atmosphere inside and out is very welcoming.

There are a lot of choices in this area when it comes to beers and outdoor seating in a dog friendly environment. But this place is brand new and the staff are extremely nice and that goes a long way. I think that is the difference maker when there is so much competition. This place is great and if you are in Sunnyside you should become a regular here.This place f$#@in slaps.

Great space to hang w friends/family. Yummy tumeric latte but it was early and out of bagels and gf bread...menu mostly bagel sandwiches

Great place to hang out. Coffee was great also

Very awesome vibe and great coffee

It seems like this place has new owners every month. What is going on? Used to be great, but has gotten progressively worse.

Good coffee, good service,and great atmosphere both inside and out. Havent tried their adult beverages or their food yet.

I was really bummed when Common Grounds announced they were closing shop, but I have to say I’m pretty enthusiastic about Radiator. It’s like CG’s cool younger cousin moved in and (finally!) brought some good bagels to the neighborhood! Great indoor/outdoor atmosphere that’s fun for casual breakfast or happy hour. Welcome to the Sunnyside — glad you’re here!

Nice neighbor coffee shop and bar. Big patio that allows dogs.

Awesome bar tender, great atmosphere.

Radiator is a welcome addition to the neighborhood. Theyve done a great job with safety precautions and social distancing, so Ive been working from here in the mornings. Great coffee and breakfast items all around.When Im ready to head home, I grab some of their lunch items for takeout. I cant wait to come for dinner or with friends for drinks. Great job Radiator team!

The Radiator is off to a strong start becoming THE neighborhood spot.The massive patio area with ample seating is the perfect space to enjoy a morning coffee with your doggo, a working lunch, or a late night drink. The coffee is great, the sangria (esp. the red) is fantastic and not too sweet, and theres a solid selection of draft and bottled beer, including a few Belgians that you cant find everywhere. Service is also excellent and very friendly. I highly recommend checking out The Radiator; Ill be back morning, noon, and night.

Super cute / chill cafe! Staff was amazing. They gave out burritos they didnt sell vs throwing away (yes please). Great variety of alcoholic beverages. Their little patio set up is legit. Had a great time, you should to. Go to The Radiator.

Great relaxing brunch with my lovely Vanessa. 💕

Stopped in with my brother to check this place out twice last week and was pleasantly surprised. Sunnyside has really been lacking in a spot like this that does the all day cafe type thing with breakfast + coffee in the AM, lunch and then transitioning into drinks in the evening. So far weve tried out the breakfast (the breakfast burritos are really solid) + ice cream in the evening and anticipate well be back often in the future.Sometimes with places like this that are trying to do so much (breakfast, daytime work space, dog friendly, bar in the evening etc) they sort of cut corners, but the Radiator seems to be taking all of their offerings seriously (from using Leroys bagels to having a thoughtful beer list). Great addition to the neighborhood!

My first time here and we had an amazing time, Chase the bartender is fantastic and will definitely be back!!!

The Radiator is our new fave spot in the neighborhood. They have amazing bagels, coffee and soft serve during the morning/daytime and booze in the afternoon/night! Great spot to bring family, friends, and dogs. Food trucks come on the weekends also!

Overpriced everything. Bourgeois bar to say the least.

Very cool date spot. Nice atmosphere, good coffee and service.

Radiator is a really cute cafe with good coffee and food. Highly recommend the bacon and veggie sandwich!!

Such a cute little spot! Went in for a bagel and was not disappointed - dare I say better than Rosenbergs? They have an awesome selection of cream cheese too. Everything - including the booze - was super well priced. House wine and sangria for $6, etc. Can’t wait to check it out for happy hour - so many great seating options outside and in.

Delicious bagel sandwiches and a tasty latte! Cant go wrong with that! Staff seams nice and the space is both stylish and cozy.

Sandwiches and bagels but get here early!

Apparently my last review was taken down, which is pretty lame. Gave them two stars, but today’s visit and my missing review knocks them down. Music loud like a night club. Still a bad environment, depressing astroturf, ultra norm core environment, and makes me miss Common Grounds even more.

Pretty nice place with a lot of outdoor seating and some good coffee, food, and drinks. Becoming my go to place to work during the day.

Friendly staff, great atmosphere, clean.

Go-to bring your laptop and crush work place

This place is a disaster. Nobody knew if the bartender was even here, they dont serve hard alcohol, their beer was unavailable, they had multiple options on the food menu unavailable, the service was very slow, and the staff were not very good vibes in general.

Really great vibes and comfortable seating areas - coffee is a bit mediocre to me and beer selection isn’t great, but it’s a lovely work spot which kind employees and tons of outdoor seating !!

Favorite coffee spot in the vicinity

Great wine selection/value and the breakfast burritos were some of the best Ive had! Great energy from crowd and service was excellent. Will be back!

I had low expectations from what I heard from my neighbors, but wow is an understatement. The bagels are slapped together in a rush (understandable since they seem understaffed), but tasted decent. Made the mistake of getting a burrito for my wife. Tasted like it’s been sitting in a warmer for a week. But the rude lady (Meghan?) insisted “bUt ItS lOcAl”. Threw it out. I’d have given this place another chance if she wasn’t so obnoxious to us and her staff. Seemed apathetic to the disaster going on. Hard pass.

This place is amazing! The vibe is trendy, casual, chic coffeehouse & bar.COVID: They are taking great COVID precautions - they have a big tent set up for more open dining, they take your temperature at the door, and can open the big garage door windows for more airflow. The patio is huge and very spread out.Food: Great bagel sandwiches & breakfast burritos (served all day). Do yourself a favor and get the Caprese..so good.Drinks: Full coffee menu, great beers on tap, wine, and sangria! The red sangria was fantastic.I will definitely be heading to Radiator on warmish Denver days to sit out on the patio or even on chillier days to sit in the tent. It feels very safe.

Awesome atmosphere, great local spot to grab a coffee or beer. Also has soft serve ice cream!

Very pleasant, great staff, will have food soon. Great beers on tap. Nitrogen mix to maintain carbonation.

Great place for coffee and drinks!

Great atmosphere, great service, the best neighborhood spot for drinks, coffee, etc. outdoor space where you can bring your kids and dogs. Love this spot

Great new spot. Twas a beautiful day to sit outside!

This place is awesome! Such a good place to hang with the pup and get some work done or grab an afternoon beer. Stoked on this place!

Great hang out. Read a book in the afternoon,catch a buzz at night. Very hip

Beautiful decor, delicious drinks and food- the owner is an absolute doll and I think this place is on the path to becoming a neighborhood staple and favorite.

Sunny, comfortable, pleasant staff ie. my new Sat. afternoon drinking spot.

Hella good coffee and cool atmosphere

Bagel sammies and mochas are delicious and its a comfortable place to work for a morning.

I had a Very nice veggie burrito and peppermint tea at a reasonable price and very friendly service and an open air setting in this beautiful restaurant.

Great neighborhood spot for coffee and best bagels around!!

Sweet rotating beer and wine selection to keep things fresh and interesting. That watermelon sour and sangria tho 🤤😍

We’ll be back! Great spiked apple cider!

Always out of bagels it’s ridiculous, they are open until 8pm and run out of bagels by 10am... figure out your supply and demand.

Great food and nice staff.
