In the evening, it offers unlimited orders of 15 kinds of sushi, including lean, medium-fat, and fatty bluefin tuna, for 60 minutes. It is a 4-5 minute walk from Tsukiji Station, and sushi is served directly at the counter, with food coming out quickly after ordering. The tuna sometimes has a fishy taste or retains sinew and discolored parts.
