In an area that teems with sushi bars, this one maintains its reputation as one of the best. Edo-Gin serves up generous slabs of fish that drape over the vinegared rice rather than perch demurely on top. The centerpiece of the main room is a huge tank, in which the day's ingredients swim about until they are required; it doesn't get any fresher than that! Reservations not accepted. Subway: Hibiya Line, Tsukiji Eki (Exit 1); Toei Oedo Line, Tsukiji-shijo Eki (Exit A1).
