A wide selection of bubble tea to choose from, very well made tapioca, and incredibly creamy bubble tea. Chatime appears to be very clean as well, which is something you won't find at most Tea Shop 168 locations.
The one downside, as with most places that offer such quality of their competitors, is the huge line you'll find, usually leading right to, if not out the front door and around.
Give it a try though if you have 20 minutes to burn. It's undoubtedly the best bubble tea in the city.
