    Turnip Cake
    Mary L.

    As a Taiwanese food lover seeing this newly opened restaurant in Milpitas, I placed a larger order online for pickup with a preferred time. Straightforward business here. Parking can get congested during busy hours inside this tight plaza. I walked in 10 minutes early and got my order 5 minutes before the scheduled time. Not bad at all. Clean, organized, modern, and good interior with plenty of tables and chairs. Great place for dining inside. Food prices/bento boxes are in the higher range, but beverages start $5-$6 are considered affordable for milk tea and other items. Good impression. My takeout experience wasn't the best though. I hope they pay attention and do something better about the way they pack up bento boxes and sauces or sugary toppings. Boxes were extremely difficult to wash off and pretty random cheap for bento boxes. They need better heavier duty boxes to hold saucy foods. Food portions exceeded the box hold size and they used a rubber-band to hold the boxes. I had to do a huge cleanup of everything on my countertop and transferred foods to clean plastic containers to hold the droopy oily sauces before eating. Foods were all legit, delicious, and good in flavors. They do give you huge portions with a lot more sauces topped over the foods than most places, so it does get messy. We liked their foods and would consider dining inside next time instead. The packaging with overloaded sauces spilling over the boxes was overwhelming. Interior upkeep is cozy and comfortable in atmosphere. At least they have good selections on the menu. It's something worth looking forward to. Good lunch. What we had were all 5/5 good tasting here. -Chicken Curry Cutlet Rice (huge). -Three Cup Tofu Bento (overly drooped with basil sauce + vegetable sides were different from images shown on the menu). -Grilled Taiwanese Sausage (garlicky). -Turnip Cake (decent with dipping sauce). -Fried Mochi Ball (made well/sugary peanut toppings were generous).

    02 Valley a newly estabished Taiwanese restaurant is making its mark in Milpitas serving Taiwanese bento style meals at a shoestring budget aling with boba/fruit drinks. Came by on a Friday morning greeted with a friendly smile so inviting placing an order via QR barcode, on-line or self-servuce kiosk tipping is optional. I chose to dine-in order R13 minced pork rice with protein base veggies at a price of $14.98 and passion fruit green tea regular ice less sweetness for a price of $5 unbelievable large size cup so refreshing. Definitely my go-to minced pork rice cook perfectly generous portion. Highly recommend to my co-workers and friends. Ample parking in an area with so few surrounding shops so please support your lical business.

    I saw this place when I was scrolling through instagram reels at 3 am so I decided to come out here to try the popcorn chicken. For about $13, it's just a little bit more pricey than most popcorn chicken but I liked the seasoning on it and it was very crispy. Definitely going to come back if I'm feeling popcorn chicken and maybe to try their drinks and bentos too.

    A very nice, small, cool space for a drink or snack. It was empty at the time I was there, but there's plenty of seating and it's all clean & in good repair. The staff answered my questions in a friendly and straightforward manner. I ordered an oolong milk tea and an order of fried sweet potato balls. I've never seen that on a menu before and since I love sweet potatoes, I had to try it. They were purple and gold, so they looked good AND tasted good. There's a little table set up with condiments and napkins, etc. I got a little bit of sweet chile sauce to dip them in and it was even better! The tea was basic, but so was my order, no complaints. It was a hot day so I appreciated the AC being on for me to relax and enjoy my midday snack! I'd definitely come back to try more of the tea varieties and more sweet potato balls!

    Very nice, clean and cozy restaurant, staff were very friendly to give me a rundown of the menu. It is self serve for the most part but the food was very good. The popcorn chicken bento was delicious with crispy fried Thai basil, the chicken was marinated very well and the veggies were not soggy at all. Highly recommend this place for a comforting meal on the go :))

    I've been here several times and I'm not even from the bay area but omg... I would do anything to…read moreteleport back to Milpitas and chug their drinks again and again. I've tried the following: Mango matcha (10/10) - My absolute favorite! I am a big fan of the mango puree.. I feel like I haven't encountered any other mango matchas with the same flavor profile as this. The puree feels eerily familiar and nostalgic. Just the right sweetness. Matcha is strong. I close my eyes and think about all the good in the world when I drink this beautiful fruity concoction Banana pudding matcha (8/10) - My bf likes this drink! Personally I am not as big of a fan of banana matcha but he loved how there are crunchy breadcrumbs(?) on top of the cream paired with the strong matcha as usual. Feels more like a dessert than a drink lol Raspberry cream matcha (7/10) - This also felt more like a dessert. I was surprised that the only matcha part of it was the cream top (so it's not a matcha latte). Would recommend this if you are into fruity creamy drinks where matcha flavor is not necessarily the main star of the show Service is standard, you don't really interact with the workers as you can order online or via the kiosk without ever having to talk to a single person if you're feeling antisocial. Interior is bright and cutely decorated/minimalist I will be back. Mark my words.

    I've been here a few time to drink their matcha and Hojicia. They definitely make great…read moreHojicia.Today I came to try their seasonal drink. Strawberry cream matcha (3/5): This matcha drink has a strawberry cream top. The strawberry liked a bit of flavor. The matcha was very rough. Definitely not my favorite drink

    One of my favorite boba shops in the Bay Area -- absolutely worth a visit!…read more I've been to quite a few boba shops around the Bay Area, and UMe Tea is definitely one of the places that really stands out to me. This is the kind of place where you have a great experience and genuinely want to come back again. I work out regularly and pay quite a bit of attention to what I eat and drink, so I'm usually pretty careful with sugary drinks. In the past, I often found that boba drinks could be way too sweet or heavy, and after a few sips I would already feel like I'd had enough. What I really appreciate about UMe Tea is that their drinks can be customized, and the flavors themselves are actually very enjoyable without relying entirely on sweetness. For my recent visit, I ordered the Guava Strawberry Sticky Rice Yogurt with 30% sugar, fixed ice, and oat popping boba. It was SO good. The guava and strawberry flavors were fruity and refreshing, while the yogurt gave the drink a smooth and slightly tangy flavor. The sticky rice added a really interesting texture, and the oat popping boba made every sip more fun. What I especially like is that the drink has multiple layers of flavor and texture. It doesn't just taste like sugar. You can actually taste the fruit, yogurt, and toppings separately, and everything works really well together. As someone who works out regularly, I really appreciate having the option to customize the sweetness. 30% sugar was perfect for me, and I never felt like the drink was overly sweet or heavy. I also ordered the Popcorn Chicken / Salt & Pepper Chicken with the Spicy Chili BBQ seasoning. The chicken was crispy on the outside, flavorful, and paired really well with the drink. But honestly, what makes me want to come back isn't just the food and drinks -- the staff at the Milpitas location are fantastic. Everyone was very friendly, welcoming, and genuinely nice. The service felt personal rather than rushed, and the staff made me feel very comfortable. The manager and the employees were especially friendly, and you can tell that they care about the customer experience. That matters a lot to me because I'm the type of customer who will keep coming back to a place when I know I'm going to get both good food and good service. I also really like that UMe Tea has options for people with different preferences. Whether you like sweeter drinks, lighter drinks, fruit-based drinks, yogurt drinks, or different toppings, there are plenty of combinations to try. I'm someone who enjoys working out and eating relatively clean most of the time, but I still want to enjoy a good drink occasionally. UMe Tea is one of the places where I feel like I can do that without having to order something ridiculously sweet just to make it taste good. Overall, this was an excellent experience. Great drinks, unique flavors, customizable sweetness, delicious snacks, and genuinely friendly staff. I will definitely be coming back and trying more drinks from the menu. I'm already thinking about what combination I want to order next time. Highly recommended. If you're in the Milpitas area and looking for a really good boba/yogurt drink, definitely give UMe Tea a try. They absolutely deserve 5 stars!

    I was in the area looking for boba, and while there were others in the same shopping plaza, I…read morehonestly only stopped in because I saw a huge pink blow up bunny in the front and had to go in! This shop is super cute, lots of pink everywhere and cute merch for sale. We got the popcorn chicken, Coco Mango, Oreo Cream Brulee Boba Oolong Milk Tea, Lychee Tea and Sticky Rice Black Milk tea. Everything (with the exception of the lychee tea - too sour) we got was soooo good. The popcorn chicken was piping hot and crispy, the drinks were a perfect combination of ingredients. My entire family really enjoyed everything we got. I don't know if they still offer it, but I ordered my drink in this super big "surprise cup". Basically it's like a happy meal, where you lift your actual drink cup to reveal a toy on the bottom of the bigger cup. I got two avocado plushie bag/key chains. So cute! Love this chain, wish they would expand to SoCal. Why is it not a 5 star review? The only downside is that the wait is SUPER LONG! I walked over to the 99 Ranch to pick up a few things, and I came back and my drinks still weren't ready. We waited about 45 min for our order. Boo...
