Service is quite bad. I came here a few times but yesterday night, I went with a few friends after dinner. I wasn't hungry or thirsty so I opted out of getting anything while my friends ordered.
So here's the ridiculous policy they have: each person has to buy something otherwise you can't sit in without paying $3.49. It wasn't even busy but I'd have a little more sympathy if it were a busy night.
I'm sorry but that's just crazy. Maybe all other bubble tea shops are like this. I'll have to get back to you on that one.
