Heungdo Sikdang is a tonkatsu restaurant in Seoul that serves thick Japanese-style pork cutlets. Hirekatsu, roskatsu, and modum katsu come with curry, wasabi, and salt on the side. The dining room has only 10 seats, and a party of four was waitlisted at 12:10 PM. Cooking after ordering has taken over 30 minutes, and the narrow space makes the seating feel cramped.
