Sushi Dengoku is a conveyor-belt sushi restaurant inside a department store in Seoul, serving sushi, naengmyeon, and karaage. Items not on the belt are made to order by the chef, and sushi sets and kaisendon are also served. It opened in the space where Gappo Haru used to be, and the interior was newly built with a 40-year, three-generation tradition behind it. Food takes a long time to arrive.
