While the current trend in noodles may well be ramen, this bafflingly-named Japanese restaurant just ten minutes from my apartment specialises in udon. Unless you are my friend Diego Zambrano it will probably take you several visits to get through all the things you need to try on the menu - the gyoza are otherworldly, the sushi 'tacos' clever enough without being silly. New York has thousands of awful Japanese places; this is not one of them. It's super nice to come in on a Sunday night and eat at the bar next to curmudgeonly old guys barking at each other in Japanese.
I live above TriBeCa and take walks into and around this area often. It's quiet, usually on the emptier side, and hosts a few gems of restaurants including Tiny's, Takahachi, and Odeon - all on the same block of West Broadway.
