Katsumi is a tonkatsu restaurant in Hongdae, Seoul, serving gyukatsu, steak don, and curry. The gyukatsu is cooked piece by piece on a table grill, and the steak don comes with cabbage salad and doenjang soup. Diners choose between regular and jumbo sizes, and side dishes can be refilled. The grill flame is weak or goes out often, so cooking the meat takes time.
