Tsukoi is a Japanese restaurant in Seongsan, Seogwipo, on Jeju, serving Japanese-style grilled meat and izakaya dishes. The menu includes mixed meats, okonomiyaki, and options that add ramen or motsunabe to ttak-saeu. Meat is grilled slowly and kept warm rather than served cold, in the Japanese style. A solo diner may be moved to another seat if the seat they were waiting for is given to a party of two.
