Books to read

I stopped by on a Saturday afternoon. The place was not very busy. Store was neat and well organized. Boba milk tea with puff cream was my drink. It was a nice drink. I went for 25% ice, I should have gone for a bit more. Chocolate waffle was delicious. There were kids books to read, which was nice. Nobody was reading though.

strawberry shortcake smoothie with Boba (no caffeine)
Alex G.

so good! I took my 2 littles to grab a fun drink and waffle. The kids shared a strawberry shortcake smoothie with Boba and they loved it! no caffeine! We also ordered an Oreo waffle and OMG it was so good. warm and crisp with a puff filling. the service was also great. They were happy to accommodate splitting the drink into 2 cups for my young kids. They also have board games and books in store which makes it a fun experience

house thai tea

Egg waffle was standard and tasty, crispy exterior with soft chewy interior. The chocolate flavor was pretty good, reminded me of a brownie. The drink (house thai tea) was pretty disappointing, so watered down and basically tasted like watery creamer :( No tea flavor at all. Get the waffles here but skip the watery drinks.

I like Happy Lemon a lot. It's a good safe option for me. I like the creaminess of their milk teas. If it's earlier in the day I get the regular boba milk tea with no sugar, otherwise I get the jasmine milk tea with boba. This time I went my boba was a tiny bit overcooked (not that chewy) but I still drank it anyway! Hopefully they're a bit more chewy next time. They have magnetic Scrabble which is pretty fun!

Mango sago has grapefruit but isn't listed or they just messed up my drink and added it in

Love the app so I can order for pickup and save time. Bonus is buy 10 drinks and get one for free via the app. So far the 2 I have gotten I was able to change it to 50% sweet but my daughters lemon slushy didn't have that option. Today I order a mango sago at 50% with egg pudding but tell me why there were chunks or grapefruit mixed into my drink?!? I wish this ingredient was label into my drink order. It is a some what bitter fruit to have surprise you in your drink .

Bogo

New boba shop at Belmont. This is the newest Happy Lemon at Bay Area. It has buy one get one on Feb 22nd and Feb 23rd 12 PM To 8 pm. It is grand opening day. Line was not long when we arrived at around 3 pm. Youbcan order using the touch screen or order with the cashier. To order via the kiosk, you have to create account via Happy Lemon app. You don't need it if you order with cashier. All drink is bogo. Interesting is any second one you order is free regardless if it is more expensive than the first order. Wait time will be a while as there are many orders.

Busy this grand opening weekend!

New Happy Lemon in Belmont! Plenty of easy, strip mall parking. Two self order kiosks or place order with cashier (available but less obvious until I noticed another customer do it). Kiosk was a bit glitchy, and required membership to get the BOGO deal. Fortunately, I love Happy Lemon since my first sip in Taipei and am a member, of course! 5 different types of bubble waffle here as well as their usual drinks. Four tables and seats available for groups at this location. It's grand opening weekend so drinks took awhile and staff was busy but friendly. The happy lemon app doesn't recognize this location yet, as of 2/22/25 nor does GPS for that matter. Address is 850 Emmett Ave. I learned about the grand opening from their Instagram.

Service was fast. Simple ordering and pickup. Great seating layout. Drinks were tasty, milky and refreshing. Highly recommend.

Grapefruit Yakult
Amy Z.

I love getting the grapefruit yakult from happy lemon, the right sweetness and it's not watered down. I love the kid friendly environment here at this location, comic section area, with tons of board games set up, and magnetic scrabbles and checkers. It was easy to order on the kiosk and the staff was very fast. Got my drink within 5 minutes.

Order label

Came in 2nd or 3rd day of opening. I was the only one in there except for two other small parties that followed shortly after. Ordered two drinks but had a problem with only one, A2. Black Tea with salted cheese w/ boba added also shown in the photo. No cheese foam and no boba in my drink. I don't go to happy lemon often but I wanted to get something for my partner and her drink was fine. I did not know that the different tops would indicate cheese foam or not. Disappointed when they weren't busy and messed up my order.

Came on 2nd day of grand opening. Very good location. However, Parking was hard. Super narrow for SUV car. STORE: Store decor is super simple. All white with little of yellow. Furniture are clustered with different pieces from different set. Only 2 laminated menu. Super sticky, and dirty. DRINK: No Milk tea available T_T. Self order kiosk were off. Menu is very limited. End up Ordered 4 drinks. 1. Roasted oolong tea with salted cheese: tea super watery. Salted cheese very liquidy. 2. Mango green tea with mango boba: tea super watery, all syrup. Boba was hard. 3. Lemon green tea kumquat: all syrup is in the bottom. Super sour. They forgot to shake?? 4. Mango matcha smoothie: the best of the rest but quality still ehh. Service: super quick. They don't have togo bag. The only bag that they can provide is the vegetable bag in grocery super market. :( Might back to try milk tea. But not for all the drinks above.

Boba milk tea with puff cream

Delicious boba tea, great location and warm, welcoming staff! What's not to love!!?! They just opened and I am not sure the people of Belmont have quite registered them yet. They are located right across Panda Express close to the Safeway on El Camino. Very convenient location- lots of parking nearby and you can easily weave this into your grocery run. Service was pleasant, quick and I was in and out in under a few minutes. They have a few tables if you want to hang around and enjoy stuff on location too. And best of all... their bubble waffle!! Sssooo good!! A delightful addition to Belmont!

We were running some errands in the peninsula and I needed my boba fix. I remember having a good…read moreexperience with Tea Hut SF years ago (before I became Yelp Elite), and saw that San Carlos had a location as well. The shop itself is small, and there is only one ordering kiosk. There are no bathrooms available, but the singular staff member told me that I could use the bathrooms at Peet's next door. There's not much in terms of ambiance, as it seems that it's expected you take your drink to go. I went with the jasmine matcha. I liked that there was an option for oat milk without any surcharge. Even though there was only one worker, my drink was made quickly. However, it was also the middle of the day on a weekday, so I was one of only two patrons. I'm not sure what matcha they use at Tea Hut, but I liked the flavor, and the jasmine tea was nice and florally too. Overall it was a well-balanced drink and quite refreshing for the unseasonably warm March day. I will be back to try other drinks if I'm ever in the area again.

Ordered a osmanthus rice milk tea with Boba. Not a good experience and pricey tea! Tea is. 7.75…read morenot including the boba toppings which vary in price. I was drawn to the real milk and cutting down on artificial stuff was appealing and chose to try them out on a warm afternoon. The wait was long, the seats were sticky and place not particularly clean. Reason for two stars - the tea. The rice was sour and weird tasting flavored syrup. The cup was a third filled with the rice and then boba. With regular ice, there was hardly any space for actual tea inthe 24 oz cup. so barely. 4-6 oz. of tea to drink. I asked for minimum sugar, there is no zero sugar option, that thing tasted sweeeet! Really disappointed.

cafe kazka is such a hidden gem in foster city! my friend and I came to check it out for lunch…read moreafter hearing it was a hong kong-style cafe, and were not disappointed at all. first, the cafe is so cute and also spotless- I could've stayed all day just reading or doing work. there was lots of outdoor seating overlooking the water which was so nice! I got an iced HK style coffee + milk tea which I've never had before but was so delicious. I'd definitely come back to try the other fruity drinks too! we ordered the tom yum noodles, preserved vegetables & pork noodle soup, salt & pepper fries, and the HK style french toast with peanut butter. the french toast was our favorite- it was fluffy and chewy and was just like the HK classic. the noodle dishes were both so hearty and flavorful too, and the portions were a good size. it did take a bit long for everything to come out, but it did seem like there was only one person working and she was very kind and accommodating when we had questions about our order. we didn't mind at all, especially sitting outside and enjoying the view! overall, I'll for sure be back for the drinks and to try some other HK style street food.

I stumbled upon Cafe Kazka when I was in the same plaza shopping at Osaka Marketplace. I like HK…read morestyle drinks, so I was excited to try it out. We were initially going to just stop by to grab drinks, but decided to sit down and order a few snacks as well. The location is right behind Foster City's Central lake and the weather was nice, so we decided to sit outside. We ordered the HK style milk tea, OG lemon tea, french fries, and the siu mai. If I just ordered the drinks, it might have been a better experience. The fries were okay, nothing special - they were a bit softer than I like. The siu mai was just bad. I'm not sure where it comes from, but it was gummy in texture and tasted like frozen food. There were only 5 small pieces and we still couldn't finish it. The drinks were priced fairly, but the snacks were overpriced for what it is. You order at a kiosk so there isn't much service to talk about, but we did have to ask for a ketchup a few times before they remembered to bring it to us. Maybe I'll go back to try the actual food dishes.
