Iga Chamchi Busan is a tuna restaurant in Busan that serves only bluefin tuna. Its courses use cuts of bluefin tuna alone, followed by a pre-meal porridge, crab-flavored miso, and aged pickled radish. Reservations are made through Naver, and confirmation before visiting is required. Sales stop once the prepared tuna and aged hoe run out, and the course meal can also be ordered as Course B.
