    I'm unsure why there's such a high rating for this boba shop. I ordered the taro milk tea with boba and it tasted like artificial powder taro coloring and flavoring plus watered down milk. The interior is also very lackluster. I would not come back to spend $6+ on a drink.

    This spot should be renamed as Rarely Do We get Your Order Correct! Been here a few times over the years. Always the same trios behind the counter. Strangely, same ambiance behind the scene. Playing some types board game or playing cards keeping their friendship alive! However, strategic decisions behind the scenes per business model, meal prep is poor, overall tastes is by far mediocre and messy. Not worth the price, not even worth as the pit stop for quick bite or sip of boba even if it is mark as the worst "Quickly in town". Overall, still give them a Three Stars, for their good vibes, three trips youth giving their best as entrepreneurs running business and their own business experience!

    Okinawa Milk Tea

    Tried Okinawa Milk Tea. Loved mild tea flavor with boba. Service was quick. Ambiance was okay.

    Having moved out of San Mateo back in 2020 during the pandemic, I had no idea a new boba shop opened on this side of San Mateo. Having tried basically all the other boba places in San Mateo already, I decided to give RareTea a try. Super glad I did, because they offer a good-sized cup, generous amounts of chewy and delicious boba, and are reasonably priced (without charging extra for no ice). The inside is pretty spacious and has several tables for indoor dining. Ordering is done through a self-service kiosk. When I arrived on a Sunday, the place was not very busy. But there was a number of people behind the counter playing board games with one another. I can only assume some of them were friends with the barista. Otherwise, they are definitely overstaffing only to have their staff just play board games.

    Kiwi Fruit Tea

    I have a boba/tea addiction and consider this spot my spot (I think they'd consider me a regular at this point too). I've actually turned on a bunch of people to the specific location and we all agree - they're just that good. Prices are very reasonable and quality of tea is good. Staff is friendly and helpful - gives off fun Gen Z Millennial vibes inside with the music and board games. I've seen highschoolers at the tables playing games after school. As a frequent visitor (with my coworkers), they've taken time to know our names and drinks. I love that they can do 10% sweet, which not a lot of places can do. At this point, I honestly recommend the whole menu, but here are some of the regular orders that I mostly stick to: * kiwi fruit tea zero sugar osmanthus jelly * iron goddess tea no milk add snow cream and crystal boba 10% sweet * any of the matcha milk teas Rooting for this location

    Made a quick stop in San Mateo for some boba, and this place did not disappoint! The boba had the perfect texture, and the menu was packed with a variety of teas, coffee, and tasty snacks. We couldn't stay long, but I loved that they had games available--it'd be such a fun spot to hang out with a friend or a group next time!

    Boba

    Best place the mood is awesome and boba is delicious highly recommended also boba is the best

    A pretty standard boba tea place. It's kinda quiet on a Sunday afternoon. The service is quick. At least they don't charge you extra when you want to choose no ice food your drink. For macha latte, they add fresh milk, not the non-dairy creamer nonsense. I also like they don't pre-add sugar in macha so I can choose the no sugar version. If you are in the neighborhood, definitely, check them out. The store it's pretty spacious too with quite a few seats available.

    Taro Milk Tea

    Cute inside, easy kiosk to use, I like the little game corner. The popcorn chicken was really yummy, interesting breading technique and very flavorful. Taro was chill, nothing to write home about but satisfied my craving, boba good texture.

    Jasmine green milk tea and Taro milk tea
    Anne S.

    Stopped in to try their Taro Milk Tea and Jasmine Green Milk Tea. Both came with freshly made boba, still warm, and were made to order--less sweet, light ice. Ordering is through a self service kiosk which makes things quick and convenient. Service was friendly. It's a small space, but there is indoor seating and board games available.

    Teapresso Iron Goddess (TGY)
    Lauren T.

    The Teaspresso - Iron Goddess (tie guan yuan tea) is pretty good, and the boba is a little on the firmer side.

    I got the classic milk tea with boba and matcha milk. They were both watered down, the boba was very soggy. Couldn't really taste the flavor of matcha. Staff were nice and efficient

    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.
