Gikku is a Japanese restaurant in Bangbae-dong that serves Korean-style sushi and sashimi courses. The lunch omakase places rice and seasonal hoe simply, followed in order by blue-backed fish such as mackerel and halfbeak, pufferfish jjim, siru, and steamed egg. The restaurant moved from Ichon-dong to Bangbae-dong about five years ago, and reservations are required before visiting. The courses come in many types and portions, so you are full by the end.
