After my third visit to Chatime, I'm really enjoying it! They have such an extensive menu-- so many flavors and styles to choose from and you can even choose how much ice and sugar you want added.
My only issue is that as someone who doesn't like very sweet things, even with 0% sugar, I find the drinks to be quite sweet. This may be due to the fact that they use syrup to add some of the flavoring (I saw them do this with the Coconut Milk Tea). Still delicious though :) Perhaps they have other options that are flavored without the use of sweet syrup.
It's also a good place to casually study. They have an upstairs with quite a few tables that is well lit due to the big windows and has a nice, clean ambience. Also a great place to sit and chat with friends!
