Haerang Sushi is a conveyor-belt sushi restaurant on the basement first floor of the Yonsei Building near Seoul Station. You can pick sushi from the belt or order separately from the chef, and the lunch set comes with sushi and udon or small fried shrimp. During lunch hours, arriving late means waiting in line, and the owner explains how to order. There are not many seats, so it is difficult for many customers to enter at once.
