Katsuou is a tonkatsu restaurant in Seoul that also serves donburi, curry, and ramen. Its tonkatsu is thick meat in a thin fried coating, and the mixed katsu comes with loin, tenderloin, cheese, and shrimp. The restaurant has a toilet inside, and on Saturday lunch customers keep coming in, with one or two parties sometimes waiting. The meat is cooked through like well-done and the coating is sometimes burnt, so it is overcooked.
