Tendong Sikdang in Seongsu is a Japanese tendon restaurant that serves rice bowls topped with fried anago, squid, and shrimp. The karaage tendon comes with karaage, rolled egg, kkwari peppers, eggplant, seaweed, and sweet pumpkin. Orders are placed on a tablet at the table, and at lunch the line moves quickly even when one forms. The shop is small, so the tables are not spaced far apart.
