For general/other topics related to tea.
There were two TenRen tea shops in Chinatown when I was in NYC a few months ago. The store on, I believe it was Broadway, was in the process of shutting down. As far as I know, the other store (which I have never visited) is still there.
The one in flushing us there just picked up some dark oolong from them. And people are there are giving it great reviews n tons of service. Probably wont close anytime soon.
