Cute little coffee shop with interesting options. I tried the iced turmeric latte with oat milk and my friends had latte and cappuccino. We all enjoyed our drinks but I think mine could’ve used slightly more turmeric. Definitely recommend this place.

This coffee shop is small but very cute!! They currently dont have indoor seating, but they do have a few tables outdoors. I got an iced ube latte w oat milk and it was pretty good, but a little sweet for my taste. I have also gotten an iced cinnamon honey latte w oat milk from here and it was pretty average tasting. The staff are attentive and kind, and the atmosphere is lively and hip!

Once we arrived we quickly noticed that it was a very busy friday morning and a small line formed out the front door. they made our drink correctly but besides that; the customer service was a bit lacking or at least thats how i felt. it was a generally okay experience but i expected better.

Traditional macchiato, great avocado toast. Nice people all around 👍🏻🌻

If only for the beauty of the art. I would give a 5 star. They make excellent coffee.

Wonderful choice for a party event!we invited 1 OZ to tell us about the coffee culture and to experience coffee tasting. everything was done professionally and sharply organized, cozy and stylish, clean and safe =) we didn’t have to worry about anything - the organizers came, set everything up and at the end packed everything up discreetly and neatly.all of our guests were amazed by how much these young women love what they do! we all fell in love with their passion for coffee making and high standards of services1 OZ is not only the best coffee in the Valley, but also the coziest catering and event company!

One of the very best coffees you can get in Mountain View. They brew it with love and you definitely can taste it. They also have coffee beans for sale and you can sit outside. 5 stars

Nice place with great vibes, coffee is good if you like latte, I am myself an espresso type of gal and it was gross. The espresso was bitter, salty and it had no natural foam that usually happens when you brew it (i do not recommend buying espresso here) however I tried a latte and it was better than Starbucks. I would give it a 5 stars but the espresso was a dissatisfaction.

The best coffee spot in the valley. Skillful baristas making top notch espresso based drinks. Tends to get very busy during peak hours, as all the coffee enthusiasts flock here to get their fix. Yesterday all pastries ran out early on, and I sent them an email giving feedback, to which they immediately responded that they’re gonna make sure there are enough pastries next time! Excellent customer service all around.

I tried the Affogato here. Unlike most cafes where they would have options of vanilla or hazelnut, they had pistachio gelato and that took the affogato to a whole new amazing level! ❤️ must try!It’s a cozy little cafe 2 blocks away from the crowded part of castro street so quiet and calm and you would get parking easily here

My go to coffee place in Mountain View. They also have a great selection of whole beans to take home! The offer most of those roasts for pour over on site and I have never been disappointed. When I am feeling particularly indulgent I get an affogato, which is absolutely delicious. On top of all this the staff is friendly, helpful, and knowledgeable about their beans. Plus they have had plenty of outdoor seating during COVID.

Came here on a Saturday afternoon to do some work and I really loved it! The service was a bit slow since they were busy but the latte art was great and my favorite was definitely the ube latte since it had quite a sweet taste but also had such a unique flavor. The wifi was fast and the outdoor seating was nice and shady. Would come again.

Definitely try their Almond Croissants!!

Worth the wait 👌

One of the best third-wave coffeehouses in the South Bay. Professional baristas, friendly staff, casual vibes and great music—all on top of the precisely-pulled espresso shots, finished by thoughtfully crafted, perfectly executed latte art in every cup of their coffee. The quote painted on their window, “Sip the life, 1 oz at a time,” faithfully portrays how I feel whenever I come here. I think they’re at the top of their game, and I hope they continue to thrive and succeed in their vision of transforming the coffee culture, adding authenticity and passion in every drop.

Interesting spins on some drinks, decent bakery selection. Good for a quick stop.

The Sea Salt Caramel Latte was amazing. Nice and clean coffee shop with a nice staff. Highly recommended if you are in the Mountain View, Ca area.

This is one of my favorite coffee spots in Mountain View. The baristas are proficient and the espresso quality is excellent. They make one of the best lattes in the area. I highly recommend this coffee shop.

For third wave enthusiasts, 1 oz has a rotating guest roaster selection, which is fairly unique in the South Bay. They’ve sold and prepared Onyx, Black & White, Brandywine, and many other fantastic roasters, which is nice for those that don’t spend a lot of time ordering coffee online. I’ve been here at least 100 times and have had a good experience every time. Would easily put this in competition for the best shop in the area with their experienced baristas.

Love the coffee and the cozy feel to this place. The baristas are great and know how to make a coffee just the right way and deliver quality service. Beans make a difference and they use good ones but how to balance the milk proportion is equally important and they do it very well. They have delicious pastries and love their chia pudding as well (runs out quickly over the weekend). Its slightly away from the main hub on Castro but that also means you can find parking relatively easily.

Great coffee, great pastries, friendly service. Ill definitely add this place to my regular rotation (even though its a bit out of the way for me)

The best coffee ☕ in mug.

An absolute oasis deserving full support from both single origin pour over aficionados and quick & simple espresso fix hunters. Impressive range of national roasters, efficiency & quality of preparation. Highly diverse choice of pastries.

Ordered Iced black coffee and coffee latte. They look and taste awesome! Would’ve been even better if the desk was cleaner:)

Our favorite little coffee shop! Great coffee and great vibes.

Latte was good, but tasted kind of weak.

Great coffee in downtown Mountain View.

Popular cafe with interesting variations made with Matcha and Ube. They are willing to customize based on your requirements. I got the Matcha which was authentic. But the cappuccino was the best.I wish they gave it with the warm covering provided in other stores.

Very smooth coffee and very aesthetically pleasing cafe! But its quite small, no outlet, very overpriced. I loved how hipster it is but I dont think paying for it is worth it.But they do have coffee from Devout cafe which I really enjoy, and theres different drinks Id like to try.Worth going at least once.

Their latte is great! Limited seating space inside the shop. Free street parking .

Love the coffee! Knowledgeable and skilled baristas, friendly service. Great tasting coffee. My favorite coffee in Silicon valley

Me: former barista and decently knowledgeable espresso nerdCame in for an espressoWas among the very best Ive had from a coffee shop.

Is this place delicious? Yes.But note that youll need to park in side streets and walk over. Lines do move slow but the drinks itself are super tasty. The croissant flakes beautifully and I could feel the layers of butter. My favorite drink would be the honey cinnamon latte which was not overly sweet!Be wary of the price. This is not your local coffee shop price.

Incredible quality, tasty drinks. And just the right amount of light for my morning eyes.

Coffee is solid. Good cold brew and service is fast even on a busy Saturday.

Great tiny place. Latte was amazingly good. My go-to place now.

The service was amazing kind ladies at the counter. The cold brew was awfully bitter and left a horrible taste in my mouth. I love cold brew but this just didnt do it for me....6 dollars for a pb&j croissant....oh my God not worth it.

Only bad thing about trying to enjoy a lazy weekend morning by visiting your local coffee shop is that everyone has the same idea as you do lol. So when we came to 1 Oz, the line was out the door, couldnt even fit everyone into the shop so we had to stand outside for a couple of mins before we could even get in. But after reaching the front, the gentleman at the register was super apologetic for the long wait (nice that he acknowledged it but obviously had no control over it), and then happily helped us by explaining their different types of pastry options. I wanted the matcha croissant, but they were unfortunately out and had to settle for their baklava croissant, though which he explained was actually one of their more popular pastries (they also carry Third Culture bakery mochi donuts for those interested!) For coffee, I was feelin something sweet so I went with their cinnamon honey latte.Presentation wise, coffee and pastries are served on an attractive wooden boards. And the coffee turned out to be really good! They brew Vertigo Coffee Roasters from San Juan Bautista, which roasts some quality beans. Latte tasted like a chai latte, but with coffee, honey added a nice touch, not overly sweet. Baklava croissant was also actually really good too, filling had a sweet, walnuty taste, glad I ended up getting it! Overall, this place does coffee and pastries right, not to mention friendly and courteous service!

My favourite coffee spot in MV! Their coffee’s quality is consistently good, foam is silky and the espresso is great. They also have delicious pastries.I do miss more relaxing seating areas (a sofa instead of bar chairs would be nice).

Great honey latte- not too sweet!

Great coffee, pastries and service. Definitely has a morning rush of customers so keep that in mind when planning to go here. That said, its definitely worth the wait.Open during COVID and has ample hand sanitizer for customers to use. Also has tables and benches outside for seating.

I had a wonderful cortado/Gibraltar here. Perfectly prepared, and the espresso tastes great! This shop serves coffee, espresso, and baked goods. I highly recommend 1 oz, and Id definitely return if Im back in the area.

Simple and trendy vibe. Just a short walk from Castro street downtown Mountain View area. Not very crowded but service is a bit slow. Coffee is delicious though!

Cute little coffee shop on Castro St! Bold flavors and interesting blue theme! We got a latte and a Gibraltar. Yumm. Slightly expensive but then what is not in this area????

Small coffee shop with delicious latte. Worth the stop!

Cosy small coffee place with good flavorful coffee and fresh pastry. Probably, the best tasting coffee in the whole Bay Area. The baristas know how to pull an excellent espresso and make a beautiful firm froth.

Friendly service. Delicious espresso; certainly the best Ive come across in Mountain View. Prices are fair. As far as food goes, theres a limited selection of pastries from Alexanders, granola + yogurt and some cookies.The poor guy that served us was on his own and trying to juggle everything, but he did a great job, and he apologized to every customer for the (minimal) wait.Theyve only recently opened, so its clear that theyre still getting set up. They seem to be off to a great start though!

Best coffee and the genuain California flavor avocado croissant.

I would give this place 5 stars if using metric instead of imperial system. 🤣But despite being a big fan of international unit system, Im also a fan of good coffee, and coffee here is good for sure. My cortado (or is it call Gibraltar?) was good and very smooth.Maybe cortado is in meters, kilograms and liters but Gibraltar in inches, pounds and gallons? Never thought on that before.

Amazing coffee to get when in the Silicon Valley area.

Split my coffee walking out the door, and they gave me get a new one. Very considerate staff :)))

The best coffee shop in Bay Area

A lovely artisan coffee shop that is cozy and welcoming. The coffee roast has that little extra flavor, that little better latte art, those little more generous smiles. The seating may be a problem sometimes with a few (among many) laptop users hoarding spaces, but then those few hoarders have plagued all cafes alike. Other than that I was surprised to see some genuine conversations happening over coffee, which was a delight to see.

I can only drink decaf. Cafe latte tastes okay. Slightly creamier texture than other places. Overpriced though

Amazing light roasted coffee and excellent cold brew

Love the interior design and my pour over coffee was excellent. Super friendly people.

Friendly staff with a warm, minimalist aesthetic. Stopped in mid-morning on my day off to enjoy a perfectly prepared cappuccino and a divine almond croissant. Some days Ill just grab a coffee wherever is closest, but when I want to sit down and really enjoy it then 1 Oz Coffee is quickly becoming my favorite option.

Minimalist artisanal coffee shop serving traditional espresso drinks, cold brew, and bar-none the best pour-over coffee in Mountain View!Light roast, mostly single origin beans from Vertigo and a rotating caste of other fantastic roasters. (new selection weekly)They also sell bags of beans, which come with a free espresso shot!

Great spot to study or do some work and cute latte art!

Fancy place but overpriced drinks. The vegan donut was more like a cake

So far the best coffee place in my States visit. It feels like drinking coffee in Europe and Down Under

Food was ok. We were dining in and didnt get the cutlery, and had the sandwich in the takeaway box

Excellent coffee and friendly service. Couldnt wait to taste the Gibraltar so the picture is post taste.

Cappuccino not nearly as good as it use to be

Awesome variety, efficient online queue, great staff and good coffee. Loved the gibraltar.

Delicious pastry & coffee.

Excellent coffee. Cant go wrong.I would also recommend the Croissant sandwiches if youre looking for a snack.

Cappuccinos made to perfection! Nice music and friendly staff, the place is a bit small and hard to find seats available but its definitely worth it!

Good taste coffee tonic for summer

Great coffee

Wow, awesome coffee selection and good baristas. I had a cup of pour over, an Ethiopian roast from Devout. It tasted amazing, super flavorful. Pretty bold opening this spot next door to Starbucks, but I’m assuming they’re targeting the serious coffee drinkers. You can go to Starbucks for sugary drinks and WiFi. This spot is small so it seems to be meant for people on the go, or if you’d like to sit or stand and talk for a bit over a cup.

This place lives up to the hype! Its in a good location (a block away from busy part of Castro). The place is small but nice. Price is a little high, just like every other specialty coffee place in Bay area. The coffee was very authentic, strong and potent. I tried cappuccino with an extra shot like I usually do but that made it a little too strong. Ill visit again.

Awesome cold brew

Quality coffee and good service

Good quality products - matcha latte is not overly sweet and made with high quality ingredient. Chia seed pudding is also made with fresh good ingredients and not too sweet.Slightly pricy but you would feel good with what you get.

1 Oz Coffee really nails the brewing process. I am consistently impressed with every cup of coffee I get from them, and their gibraltar is by far one of the best Ive had in the bay area.

They have a nice coffee. Recommend if like strong taste.

Great coffee shop, best on Castro street in my opinion. Would recommend to anyone!

Amazing cafe with delicious coffee and matcha green tea latte 🍵

I was craving an iced coffee and I happen to be in the area when my gf suggested 1 Oz Coffee.The interior of this cafe has a nice minimal aesthetic vibe going on, which I loved! I ordered the small iced latte, which was about $4~My drink had the perfect balance of creaminess & espresso. Perfect for a hot day or when its about to be 2pm and you need a pick me up. Very refreshing and definitely keeps you wired throughout the day.

Their coffee tastes great and staff is super nice!

Ok coffee, good food, kind of slow.

Way better than the neighboring Starbucks!

Great cup! A staple in the area.

Great coffee and service with excellent presentation!

To be honest, I loved going to this place every weekend to relax and work, but the one time I decide not to give a tip, the guy makes me a 3/4 full drink with severely over-burnt coffee. It was pretty clear he didn’t appreciate the no tip, but does that mean he has to take it out on me by making a terrible coffee?Also, since when did we start giving tips *before* the service? Does that seem backwards to anyone else?

Good cappuccino♡

Best coffee in town. Can’t drink Starbucks anymore

Delicious coffee with oat milk

I dont know how they do it! I buy nice beans, I grind them fresh, I have a Hario v60, and yet my coffee absolutely pales in comparison to their pourover.

Great new local craft coffee spot on Castro street. We need more coffee spots like this! I got a cappuccino and it was executed perfectly. They also sell Vertigo beans. Didnt get a chance to try their food, but will be back soon to give them a try.

I came in for a pastry (not a coffee drinker) but I kept hearing people say Oh my God this is freaking amazing

Amazing quality espresso and love the local art as a bonus touch.

Great coffee.. Meh service..

I love this place. It is a ritual - come here every weekend day for a cup of fresh capuccino. 😍

These people love coffee and theyre knowledgeable. So kind. Incredibly talented. This is my everyday spot and theyve def earned it. Youre gonna have some new beans from amazing roasters rotating pretty often. Def a must stop in mt view. ♥️

High quality food and drinks.

Stopped in for the first time on 4/3/19. So glad I did! I cant handle caffeine anymore, but truly enjoyed the Decaf single latte at 1 Oz Coffee. Perfectly made with zero bitterness. My test of a perfect latte is if I dont need sugar. Took my first sip and it was exactly as an excellent latte should be.They even had 1 croissant left, since I cruised in near closing. What a treat! It was still fresh like it was morning.Definitely recommend 1 Oz Coffee and will stop in next time Im nearby!

Cute little cafe located in Inner Sunset! I came here on a Sunday afternoon and absolutely loved the Iced Matcha Latte I ordered. Yay for paper straws!I would recommend this spot if you want to grab a quick drink, catch up with a friend, or get some reading/studying done. Check it out!

Good taste
