Heosuabi Donkkaseu Jeongdong is on the second floor at the end of Jeongdong-gil in Seoul and serves Japanese-style tonkatsu. Hirekatsu and the fish and sirloin set meals are the main dishes, and diners grind sesame at the table and mix it with tonkatsu sauce and mustard to taste. On weekdays the last empty seat fills around 11:35 a.m., and during a wait staff come out to check the number of people and the order first. At lunch peak the hall is full and the tables are set close together.
