Onyu is a donkatsu restaurant in Goejeong-dong, Daejeon. It serves samonim donkatsu, which is thick and tender, along with anshim, cheese, and chicken katsu, and rice and salad can be refilled. The space has the feel of a hanok house, with table kiosks for ordering and paying at the seat. At lunchtime the number of tables is limited, so a wait forms.
