Yi Seungjae Chamchi is a tuna restaurant in Seoul that serves aged tuna hoe as an all-you-can-eat meal. The first plate includes bluefin tuna belly, swordfish and bigeye tuna belly, and akami, and after the soy-marinated crab, rice is mixed in. A lunch course is available, and the thawed tuna is served tender. The first plate is acceptable, but from the refills onward the cuts and the quality of the taste drop.
