We offer Kinmedai prepared in a variety of ways-sashimi, simmered, grilled, and shabu-shabu.

Among these, the Kinmedai Shabu-Shabu is especially popular for its refined taste and vibrant presentation-delighting both the eyes and the palate. Among these, the Kinmedai Shabu-Shabu is especially popular for its refined taste and vibrant presentation-delighting both the eyes and the palate.
