amai, amai, amai. I can't say it anymore. You will leave very fufilled and satisfied.
Tafu just opened up a US location in NYC in the Doubletree hotel on Lexington-
. I tasted their Japanese teas and treats at the coffee and tea festival, and they were quite good.
I've heard of that shopping plaza, Witches Brew, but never have been. There are plenty of Asian food marts by me, but it would be interesting to go there since they are mostly Japanese foods. Their website looks ridiculous, so maybe one dya I will venture out (though I really really hate driving in edgewater and hoboken).
Chopsticks NY magazine is a good source for japanese food, which is off topic, but if anything has some ads and listings for tea rooms, japanese stores and what not.
