I admire the concept, but the execution is not quite there. Overall, lackluster. Yes, they do have a lot of exotic sounding teas in all kinds of variety. But are they "good"? - I'd say OK, based on the Sencha and white tea my friend and I had. The decorations and seating arrangements are .. ok. I know what they're trying to do, but not sure if its working.
I do appreciate the hours open (until 11pm 7 days a week), though.
