The coffee was pretty good, and they have several different types of drinks, including cold HK style milk tea with bubbles, pudding, or other kinds of jelly. They also sell coffee baens and coffee makers. The store front is quite cute, but the wait time is very long (even though it wasn't very busy when we got there).
Btw, if you are wondering what 'brownish milk' is on the menu, i overheard the staff saying that it is milk with a little bit of coffee.
