What Chatime is to bubble tea, is what Starbucks is to coffee. Chatime's a popular chain of tea shops with consistent quality and service. They also have a rewards card program and a huge fan base. And just like Starbucks, their drinks are pricey.
Regardless, it's a nice spot to catch up with friends. There's a massive menu, so don't worry, you have choices. My go-to drink is the grass jelly roasted milk tea with 20% sugar. The food selection is very limited there (a few doughnuts, I think), so I would recommend grabbing a bite elsewhere. There's a wifi and a bunch of TVs, but the TVs only show ads so it's kind of boring after a few repetitions. Chatime has a bunch of seating available, but beware of the long lines to the cashier.
Chatime's good, but not the best.
