Traditionally known as the denim district in Tokyo, this neighborhood also hides a charming/jamming seafood joint! The name means Flying Fish- so that's what you go there for- fish. No tourists, no foreigners, so we depended heavily on our Japanese friends. Great selection of Nihonshu and the quality & freshness was above reproach- just great. Service was a bit disinterested, but my buddy has a gift for getting people's attention in restaurants- so we were fine. As a foreigner I think we would have suffered more as a result of this service style. Not going to bore you with all the details but to say- if you're in the area, have some friends who can get by (or more) in Japanese- check this one out. Warmly recommended.
