Cheongu is an izakaya in Haeundae, Busan, serving aged hoe, sushi, and grilled fish. The menu centers on aged hoe and fresh fish, with an omakase course, grilled mackerel, and an assorted hoe platter. Seating is limited, so reservations are required, and the interior has wooden furniture and windows designed to look like falling rain. It is a single-room establishment, so noise from a loud table carries through the space.
