Gaegililsik is a small izakaya on an alley in Gongneung-dong, Seoul, serving tendon, sushi and donkatsu. It offers shrimp tendon, Iberico rice bowl with straw-fired meat, and sushi, while donkatsu is a limited menu item. The shop has five or six tables, so arriving before opening time means eating without waiting. Sushi and donkatsu sell out early.
