Katsumui is near Sajik Baseball Stadium in Busan and serves donkatsu and katsudon. The katsudon comes with rice mixed with pork cutlet and spicy chili, and the shop also sells donkatsu with a Western-style sauce. Orders are placed at a kiosk for counter seating, and the food arrives in one bowl with the cutlet placed on top. Seating is limited, so waits form during busy hours.
