Bad customer service. They didnt even care about my order even though i called before to make the order ahead. When I arrived and ask about my order, they didn't have it and let me wait. They served other customers before me even I called before hand. They don't let me know that they do not accept phone order. Bad experience overall and will not be back. read more

Coffee here's very good. Service was excellent, they get you in and out quick even though they're always very busy. I like their Ube coffee which I order every time i came here. read more

The egg coffee is amazing. It is worth your time to visit Da Vien Coffee. I would highly recommend you to come here.

I really enjoy the Milky coffee and boba milk tea with foam. My sister's favorite is the Pandan Milk Tea. Delicious drinks and we try to go here whenever we are in the area. read more

Ordered the egg coffee and the Ube Coffee. Asked for light ice, but they still filled half the cup with ice lol. The egg coffee was good, but falls short of the egg coffee we had at NEP Cafe. Ube Coffee was good, but it had so much ice it was hard to mix the Ube with the coffee. read more

Nice clean and homey place. Great customer service and lot of smiles. We were able to get a table outside an enjoyed an egg coffee, ube coffee and mango toast. The wife loved the egg coffee and the mango toast was cooked perfectly and was topped off with sweet mangoes and homemade whip cream. read more

Yen was a very great cashier! I got the strawberry tea and it was amazing! Very refreshing for a hot day. I will totally come back!

This place have some really good coffee such as the ube and egg coffee, but the reason why I gave this place 1 star is the service that I got recently. I've been here many times, but only to get my coffee and go, I rarely stay and sit down at the shop, but recently I took my friend to try out this place and we decided to stay and talk to catch up. We were there for about 15 minutes then one of the employees just walked up to us and asked "Is there anything else I can get for you guys?" in a way as if he was trying to kick us out because he didn't go to every tables to offer his "service" only to our table, and we only had 2 drinks on the table where as at the the tables had more than 4 people and had more than just drinks on their table. I just told him "I'll take 2 waters" and after we just got up and leave because I understood what he was doing and I felt really disrespected and disappointed for me and my friend. Now, I don't know if it's because my friend was Hispanic and that's how they treat the non-Asian customers or what because like I said I've sat down before and with my girlfriend a few times and NEVER experienced that until now. read more

Egg coffee is so good. Make sure to mix it well to understand how delicious this drink is.

Highly recommend their coffee especially the egg coffee and bac siu da. Rich flavor of coffee and right amount of ice. I DO NOT RECOMMEND the pandan milk tea b/c it's too little flavor of pandan with a lot of milk. read more

I don't know what's the hype all about for this place . It's not that good., PERIOD. I got the egg coffee but the egg wasn't prepared properly so the odor was unbearable. I don't recommend coming here for their egg coffee. If you are craving for egg coffee, just go to Nếp Cafe, it's the best imo. Another thing annoyed me is that they asked me to pay cash instead of using my credit card. Typical Vietnamese place, avoid fees and taxes. read more

Great place for coffee and good deserts. We got the Bac Siu Da (drip coffee), Flan Caramel sweet toast, Blueberry cheese foam frappe, and cheese salted egg toast. Bac Siu Da was really good smooth creamy sweet while not killing the coffee. The Sweet toast was good but didn't know what to do with the flan either put it with the toast or just on the side. Blueberry cheese frappe was also very good it's what you would expect so true to the name. The disappointment of the experience was cheese salted egg toast while it was good for a bite I think it was really only good for a bite. It was very rich and salty eating it with something sweet helped but it was so powerful the whole way. I give it a 4/5 review because I think it could show improvement but I definitely want to go back for coffee and see how the place grows. It was busy and very loud so don't expect to study there but it's a great place to go with friends and hang out. The owner (who didn't give us his name so I'm not sure if he was the owner) came by and talked to us very nice guy but didn't give us his name. read more

my first time here i got the matcha latte and i loved it so much. i'm usually afraid of ordering matcha drinks because most of the places don't have good matcha but da vien's matcha latte was actually so good. i definitely recommend this place! read more

I was coughing my butt off because I choked on my own spit (I'm dumb I know LOL) but an employee (named Zack) was very nice and handed me a cup of water. He was very nice and personable, which made me feel very welcome as I was stumbling to pay for my drinks since I was still coughing. Ai ya. The transaction went smoothly and I got my drinks in matter of seconds! I've gone here multiple times, once a week actually, so I know that their drinks are always comforting; can't go wrong with durian coffee, caramel flan coffee, and all the bingsoo flavors. I love coming here! Zack definitely made my experience so much better and I can't wait to come back here next week. Hopefully not coughing this time happy Friday yalls! read more

My favorite go to drink here is the ube latte. It has a unique taste and the ube isn't overwhelming. The staff here are really friendly and have great service. Zak took my order and was very thorough with explaining the menu. He even took time after to check in to see if my order was correct. Would recommend to come back again! read more

Nice to see my guy Zak again (we go way back, about 35 mins now) but super friendly service and great personality, drinks be super fresh my very first Yelp reviews goes out to my guy read more

Absolutely love this place! The bingsoo is so good, and the workers are so nice--especially Zak! I highly recommend trying all of the bingsoo flavors! read more

The egg coffee is pretty good, and their toast is yummy. The coffee is very strong though, so it's perfect for anyone who love strong coffee

I tried the egg and cream coffee but so far I love the cream coffee better than the egg one. Service was decent. However, it can get busy at time. Thus, expect a waiting time. read more

You gotta try their flagship coffee. One of the best in Little Saigon. Their shaved ice is very flavorful and rich. Serves two people easy.

I got the egg coffee and my bf got the caramel flan coffee. Nothing special about both drinks. It was about $6/drink I felt like I could've gotten it somewhere else for better taste at about the same price. I liked the toppings (the egg foam & flan) more than the coffee itself when I'm really there for the caffeine. Nice copy-cat, but not the same and not worth it. read more

Appreciate the homie Zack. He gave great exceptional suggestions for desserts for my girlfriend.

I got egg coffe , asked for 50% I doubt they gave 50 as it was still very sweet. I don't know what I was expecting but I know I was expecting something crazy good about the egg coffee since these reviews are so good, it's mediocre and if you don't like an eggy aftertaste, don't get it. The egg taste is stuck in my mouth lol, I'm not a egg hater but unless you LOVE eggs, I wouldn't get it again. The coffee itself is pretty nice minus all the sweetness, I will try ube next time though. read more

This place is amazing for the ice-cream and boba! Has unique drinks such as ube coffee and huge portions of ice cream (recommend sharing if ordering the ice cream). This place especially have impeccable service with friendly employees who offered to clean our table even though they didn't have to. They were also very accommodating even when it was close to closing time. read more

Came here for the third time and so excited to come back for many more times! I love their bingsoos and I have ordered different flavors every time. I got the matcha bingsoo today and it's very flavorful, if you are a matcha fan, definitely recommend this. Customer service here is awesome, Yến was very helpful and friendly to me read more

came here because our friend recommended this place, did not disappoint! ordered bunch of coffee and bread. soofull and delicious.

This spot should be considered a hidden gem in OC. I've gone here twice within the same weekend and all the drinks I gotten were so well made. The flavor of teas were aromatic, and the coffee was strong and has a smooth finish. So far I've tried their egg coffee, blueberry cheesefoam, jasmine lychee tea, and peach green tea. All were excellent! Price and quality 5 stars no questions. You got yourself a long term customer read more

I like this place but the cream to coffee ratio is just so off , today i went in and ordered a ube ice coffee thinking it would be coffee with a little cream on top but my cup was 75% cream and 25 percent coffee . read more

I've tried most of the drinks here, they are all pretty good except all drinks are too sweet. Even when I asked for 50% sweet. I asked my 20 years old niece have she try the drink here, her response "yes but I don't like it because it is too sweet". Hopefully management can look into some adjustment. read more

Coffee is great here. The only bone I have to pick is the service charge of 0.50 for being under 10 dollar purchases. If this continues, I'll just have to go to the millions of coffee places around here. You make 300% profit off selling coffee. What is 0.50 to u? Sounds petty to make this a complaint but it's about principal here. We support ur business cause u sell good products. It's a want thing. Not a need thing. Here is a thought. Let me Venmo you. Or zelle or cash app you. Those are options you can provide ur customers with service. It's 2022. And Asian places still can't get over this little hump. These fees are write off to u. Don't make ur customers feel petty and cheated. Just adding my 2 cents to that 50. read more

I tried the boba milk tea yesterday it is super good and then I will come back today soon. today I will try the caramel flan. Thank you for letting us go in the best place ever!!! read more

The drinks are good. I've always ordered blueberry cheesefoam and bac xiu da. Also, their customer service is nice

The place looks hella nice and has great service to match it. I had the egg coffee which I highly recommend. The server Goldie even ask if I was doing well. What a nice person. read more

the matcha is my go to and sooo good though the bac xiu with the pudding on top is trying to overtake my go to spot lol

This place is amazing! After reading a series of Yelp reviews, I had to give this coffee shop a try and it was the best decision. They offered the best coffee and showed the best attitude to its customers. Zach helped us out and he was very attentive and welcoming. He ensured that we were satisfied with our order. Zach provided superb service. Everything here was delicious and my coworkers and I really enjoyed this coffee spot and the service that we were provided with. Also, the Internet connection is very fast and is unlimited as well. This place is indeed perfect for studying and chilling out. For people who like coffee shops, this is a must-visit! Definitely a great first experience and I will be back again soon. read more

very friendly and nice. helped us figure out our orders and very welcoming :) the oak milk drinks are great and the coffee is very tasty! jack is a very cool and helpful guy read more

The place is small but quite nice, simple decorations. The pictures on here is very tempting for me to try it out. I ordered bạc xỉu, came out like nothing I would expected (I thought it would be dark, rich, sweet coffee like in Vn). It Just little coffee in the bottom and the rest is just white milk on top. Not sure if that whole milk or cream. Nothing like bac xiu, just like regular coffee. Price came out to be $5.17 or something, that's pretty expensive. I'm off to 7 leaves for sure. I'll give it another try someday but first time just meh read more

I had a quick visit here the other day, and I tried the Vietnamese coffee... so far it's the best Vietnamese coffee I've ever had. Super strong and great flavor--everything you could hope for. The shop itself looks really cute and clean. I would just be aware of their $10 minimum for credit cards. read more

Best Vietnamese coffee, not too sweet but coffee egg still has little smell. Im not sure if i am sensitive to smell or it supposed to smell like that. Anyway, still enjoyed it read more

Customer Service was great. The person at the counter when I went, his name was Zak, and he was great. Super nice and kind. Then again all of them are great so definitely go here if you're by Bolsa read more
