Ryoko is a tonkatsu restaurant in Hwangnidan-gil, Gyeongju, serving dishes that mix Korean and Western styles. It offers anshim katsu, omurice, noodles, and curry, and the anshim katsu comes with sauce, salt, and mustard. On weekday lunches, food arrived within 20 minutes, and salad and rice can each be refilled once. The restaurant draws enough customers that a line forms before opening or a wait develops later in the day.
