The first time we ordered popcorn chicken spicy level 4 and it was extra spicy more than we expected compared with Walnut Creek location and today we tried to order spicy level 3 and it was not spicy at all. I don’t know what’s wrong with the spicy level here. It’s so disappointed More

drinks and food are good, not very good at letting you know when your order is ready when in person, for example i ordered at 3:48 waited abt 14 mins then saw my order, i didnt hear my name called at all and it still said in progress on the screen. and it texted me "your order is ready" at 5:03...

At first glance, you might believe it's a typical boba drink pastry shop. Small space, simple design, green letter hinting of a potential vegan-esque feel and approach. … More

Y’all trippin if this is your go-to boba spot. Yes, the service is fast but the quality doesn’t keep up and the boba itself just isn’t good! I’ve given this place a fair shot, but it’s a no from me.

They didn’t announce our order out loud like all the other orders only because I didn’t tip on the order but gave a dollar tip in person. They made us wait for 2 item order for a while, I’d say 10 minutes longer than we should have waited. … More

Had the Vietnamese Matcha Cloud and the popcorn chicken (spice level 3). Both were really good. I accidentally forgot to add boba to the drink, but it was still delicious, and I don’t even usually love matcha. The chicken was juicy, nicely seasoned with a good kick, and came out hot and fresh. Definitely feels like a neighborhood staple. Will come back.

There wasn’t a straw so I couldn’t really enjoy the drinks, I had to open (messy) the cups and use a spoon. Also, it spilled all over the bag from a loose lid. They didn’t reply back so I’m here writing a bad 1 star review. Be sure to get a … More

We recently had Mr. Green Bubble cater boba tea for our office, and the experience was fantastic from start to finish. Their team was extremely professional and communicative throughout the entire process, making coordination smooth and stress-free.
The tea was excellent—flavorful and fresh! They offered a great selection, and everything was well-packaged and presented. My entire team enjoyed it, and it was a fun and refreshing treat during the workday.
Highly recommend Mr. Green Bubble for any team events or office catering needs. We'll definitely be booking them again!

Some of the best fried chicken I’ve ever had. The mushrooms, calamari and drinks were amazing. Definitely recommend trying this place.

I went here originally to get the popcorn chicken which was decent definitely think that they could have made the chicken a little bit crispier . And it was supposed to be spicy and it didn't have like any spice for it . And then the ranch that they had was like craft Ranch in a pouch . And I also got the double wings those definitely could have been cooked a little bit longer and it didn't have any flavor it just was caked on with spicy seasoning and it wasn't good . Like imagine somebody just pouring cayenne pepper on wings that's basically what it was with no seasoning . Probably won't be back again .

The purple cloud tea was 10/10. The yam tasted so fresh. Their boba is some of the better boba I've had from a tea shop, it was the perfect consistency and sweetness.

This Mr. Green Bubble location offers exquisite service and has a lovely interior with plenty of dining tables. You can order up front or at one of the Snackpass kiosks.
They offer specialty drinks as well as good milk tea (although I don't recommend their Earl Grey, which is one of two decaf options).
Prices are fair and quality is superb.

Ordered for delivery. We wanted to celebrate the end of the school week and the beginning of the Presidents' holiday week with a nice treat for the kids. We ordered from this new place (to us) and truly enjoyed the meal. We got some popcorn chicken, deep fried tofu, egg Puff pancake, Thai iced tea with boba, popping boba, and lychee bits, and lastly an oreo milk tea drink. The tofu was really good and well seasoned and fried. The popcorn chicken was well seasoned and fried too and the size of the nuggets were good for a nice mouthful of flavorful chicken. The Thai iced tea with all the add-ons was tasty but too sweet, but my son loved it. The oreo milk tea was a bit bland and not sweet at all. The egg Puff pancake was tasty and had heart shaped puffs. I didn't get a chance to take a photo of the egg Puff cuz everyone ate it all before I could take a shot at it. 🥲😒😆😅
Overall, this place is pretty good and next time I'm in the neighborhood I may just stop by and try out the food fresh and not delivered.
