I'm a big fan of the OOlong milky way tea served here; there's nothing quite like it anywhere else I've been. The selection here is impressive and the staff seems to know what they are talking about. Food on the menu is simple but well prepared and the ambiance is charming. This is a great place to meet with friends and chat for hours...I know because I've taken that idea for a test run and it works!
On a completely practical note, There is a bathroom located in the basement AND the second floor. If you're drinking tea for a few hours that might be useful information for you. Just sayin.
