One Plus Tea House - San Francisco

Worse service ever.... I don't think the Cashier speak English well enough to take the orders. I've to repeat my order three times, and guess what, it's still wrong..... I ask for 50% ice and regular sweet. She made other way around. I've waited my popcorn chicken more then 30 minutes. She didn't even realize that she didn't bring the ticket to the kitchen until I ask for it. And no apologies at all.... BTW, this is not the first time it happens.....

Teas here are extremely sweet, especially the fruit teas. Definitely make note if yoh arent a fan I usually get my teas at 30% sweetness. The milk teas are better, so I get them at 50% sweet. Cool balls are crystal boba and pretty darn good...better than most crystal boba and agar jelly I've had! If you like grass jelly, it is the best topping here imo!Service here is fast as well what you'd expect from a boba shop in Chinatown! They also offer catering orders that are super competitively priced! Def recommend reaching out if you're looking to get catering or put in a large order!

I enjoyed this little place when I went to china town. It was delicious and staff was friendly.. I went there two days in a row on my weekend there. I will definitely return..

IF I COULD GIVE THIS PLACE 0 STARS I WOULD, worst customer service and milk tea ever. I have been here for years and never have I experienced such a rude bobarista. I walked in, he completely ignored us, and took our order after 25 mins when we were standing there, I get it if he was busy, but the least he could of done was say something. Even after waiting 25 mins, I asked for the pearl milk tea, and he said I 'm not sure if the milk or boba are ready yet. Then when he took order, i saw that the sign said out of large cups but when I ordered my drink he asked me what size so I assumed they had it and just never took off the sign. Once I said large he just started aggressively pointing at the sign and yelling at me to read it. If they no large cups what was the point of asking me what size if they only had one size available. Even after placing an order, I still WAITED 35 mins BEFORE I GOT MY DRINK. I WOULD NOT RECOMMEND COMING HERE!!! unless you want to waste your money, they 're milk tea wasn 't good either.

Walking by Chinatown and suggestions from some friends, made a stop to Cool Tea Bar. I ordered the kumquat green tea with boba. The tea was very refreshing and not too sweet at 50% sweetness. It's the first time I've seen kumquat on a drink menu. The boba was chewy and good. The drink was made to order very quickly. Definitely would come back to try their other fruit teas.
