    I paid extra for mochi and boba pearls to be added into my drink. Because I ordered a slushie, and it was a thick opaque drink, I didn't notice it. It tasted like silken tofu, and thought maybe they put it in by mistake. It wasn't until I finished the drink that I realize there was no mochi nor boba pearls. I decided to not fuss about it to the staff, and just leave a 1-star review.

    If you're looking for a solid spot for late-night boba in the East Bay, Once Tea is definitely a solid choice. Located in downtown Hayward, the ambiance is pretty chill and quiet noise levels for a boba place. It's my go-to when I'm craving quality milk tea after 8:30 PM and most other places are already winding down. The ordering process is super smooth; you can use the self-service kiosks for speed or order with a cashier if you prefer. While there are only 5 tables available to sit, the service is incredibly quick, so you'll be in and out in no time. The prices are also very decent, generally ranging from $5 to no more than $8 depending on your toppings. Most importantly, the boba texture is perfect and the milk tea flavor actually tastes authentic. We got the Thai boba tea and hojicha phoenix tea latte with popping barley (hot drink). The hot drinks only come in the regular size. Didn't get to try the food, but it looks good and they had a buy one get one half off deal going on.

    The good: drinks were good and reasonably priced. Not-so-good: The place was drty and really could use some paint and fixing up. Their cute dog pillows you sit on probably have never been washed. The paint on the walls and floor was peeling. When we walked in the worker was picking his hangnails or something. Overall, not very appetizing. There's too much competition in the dessert/boba market not to clean up your act. Hard pass - yelp only ONCE.

    Would come back if I was in the area. Both drinks were good. The Mango was better than the Oreo Brûlée for sure. We ordered on the kiosk. The place was not busy on a weekend. Yummy stuff. But could be fresher! Service was ok. And inside was a bit sticky on the tables. Private lot in back

    Jasmine Milk Tea with Oat Milk
    Andy N.

    Great boba option to turn to here in Hayward that offers oat and soy milk as non-dairy milk options - a win in my book. The shop is large with many drink options and snacks to choose from. You order from the kiosk in front but can ask the staff if you have any questions. I ordered a Jasmine Milk Tea with Oat Milk and it was perfectly made. Highly recommend a lower sugar level since it's sweet as it is. They also did a great matcha latte that my sister ordered too. Will definitely come back here the next time I'm in the area.

    i just went to hayward and decided to find boba tea spot on the way home and saw once tea was the closest and i gave a try. place is just ok and there was only one staff but he was nice. i ordered mango passion fruit with aloe and surprisingly it was so refreshing and i love it!!! if you are a tea lover, i will say you need to stop by here and give it a try...

    Super Combo

    The price is very reasonable and the shop assistants are very friendly as well.And I love the fried chicken so much

    "Popcorn" chicken. No seasoning. Wrong batter
    Stephy H.

    Was craving popcorn chicken and was in the area. Their batter isn't like your typical popcorn chicken. There's also no seasonings on it... the pepper and spice is what makes it popcorn chicken. Very disappointed.

    B5. Strawberry Blizzard with Sago
    Molly L.

    We came here on a cold evening and ordered the strawberry blizzard with sago drink with boba. It came out just as we requested -- not too sweet and it had the sago and tender boba as expected. The service was fast, even though we dealt mainly with a kiosk and hardly spoke to anyone there. But overall it was a good experience and they have a lot of drink options.

    Alyssa C.

    Good boba but the shop could use some TLC. I love their selection of drinks here and I've always been happy with the value (good amount for the price). The touch screen ordering system is also really great because they have pictures of most drinks so you can see what they look like. However the store itself could use some upkeep. The floors were very dirty/sticky when I went in and there aren't great seating options to enjoy your food/drinks. Would come back for the boba but definitely would take it to go.

    F1. Peach Green Tea Lemonade with boba  A11. Oreo Brulee Boba Milk Tea (Large)
    Jennifer M.

    We were in the area and were looking for a boba spot. Hopped on yelp and saw this place had pretty good reviews & so we gave it a shot. In short, this place was just okay. The shop itself could use a paint job and some decor. I did like that they had 2 kiosks to order, and the menu seemed to have a good variety. I ordered the Oreo brûlée boba milk tea, which again, was just okay. To me it just tasted like a normal milk tea with cheese foam with Oreo sprinkled on top--not sure where the "brûlée" was. This place lives up to its name--"once"- because I don't see myself returning

    Strawberry B5. Strawberry Blizzard with Sago
    Terri M.

    When I walked in there were two girls who couldn't figure out what they wanted to get they were at the kiosk for quite some time. Luckily there's a second kiosk you can order from. It was really smoky and smelled like something was burnt inside so the employee opened the front and back doors to air it out. I ordered the large strawberry sago drink And it was delicious! I chugged it down. Wish I would have bought 2. Will definitely be back!

Parking was busy (the lot is shared with Trader Joe's) but we managed to find a spot and head into the busy but not packed cafe. There is a large assortment of empanadas, from meat options like chorizo and chicken, to vegetarian like corn and onion, to sweet options too like apples. The menu also boasts lots of great drinks including mate tea! Lucky us, the empanadas we ordered weren't in stock so we had to wait ~10 for freshly baked ones. They came out buttery and piping hot, even with little hand-stamped letters on them so you know what you're eating, and it was so delicious. Most are about $5.50 each. Add oregano chimichurri for a bit extra if you want or pair with a tea, but these empanadas really hit the snacky spot. Lots of wooden tables with fresh flowers make Pampas a great space to chat with friends or to sit and do some work. The most standout feature was the friendly and efficient staff who seem to build connections with everybody who walks in the door. Worth a drive to Castro Valley! Especially if you bring cash for a 10% discount off a dozen :)

Also while we were there, an employee was stamping boxes at a table right next to us. It was loud smacking noises that made it hard to converse with each other. I wish the employee would do that in the back or behind the counter. Waffled between three and four stars because there wasn't anything wrong with Pampas and I like to support local. But ultimately the loud smacking noises for the whole time and the fact that I didn't get what was advertised pushed me towards three.

I very much enjoy their macarons and fresh fruit tarts. They also added Banana Matcha to their menu when it became a craze, and I 10/10 would recommend it. They use high quality matcha powder (Marukyu Koyamaen) for their drinks. This is one of the few things that drew me into their cafe. The baristas are extremely friendly and have a wonderful sense of humor, AND they support small businesses! While you wait for your order, you can browse their shelf full of crystal candies, matcha sets, candles, and they may also have Natsume matcha tins available!

Their store is located in the massive plaza near Castro Valley BART station. What makes them stand out is their lime tea! They're tactfully made to ace the flavor profile, and I've enjoyed every drink I've ordered so far. Not brave enough yet to get the Hand Squeezed Lime Drink ($6.50). My sister first told me about this place, and she dropped off a Phoenix Lime Tea ($8) for me that was refreshing and not as sour as I expected from a drink with a lime ingredient :P It came in a tall, sturdy plastic cup that I reused a couple times for iced coffee at home. Phoenix Dan Cong Oolong Milk Tea with Lime Cream Cold Foam ($8): Shoot that's good. I already love oolong milk tea, and the addition of creamy lime was smooth! Not too tart and didn't ruin the taste. It came in a smaller size cup and I was sad about less drink :( Durian Smoothie with Sticky Rice ($12.50): I hate that I love durian, and it's hard to find durian drinks. Because look at that price tag!! In this economy!! I also hate that I loved it. The durian was potent (not iced down) and the sticky rice was warm, didn't harden too quickly from the cold smoothie. Gosh darn it. Durian Lime Tea ($12.50): Comes with coconut noodles as a topping! Excellent combo as well with durian bits. Can opt to have lime slices in your drink or not. Can also hear the staff hand-pounding the limes for the juice! They have 2 ordering screens, and I've seen someone order at the register as well. I like the big screen that displays orders in progress and completed ones. They have WiFi and indoor/outdoor seating if you want to work from there. I saw a lot of students flooding in during after school hours. Boba is so competitive these days and I love their drinks, so please come so they'll stay open LOL I'm curious about the Rice Mochi Milk Tea ($8) and Mango Coconut Matcha ($8.50). Thank god they're a bit of a far drive, otherwise I would have a monthly Goolu budget.

Service was super quick (although the store was empty when I went at a very off hour on the weekend). The inside has ample seating with green-themed seats/deco.
