Yeondon is a tonkatsu restaurant in Seogwipo that serves cheese tonkatsu, loin, and tenderloin. The cheese version layers meat with cheese that stretches, and the curry, made with onions cooked down for a long time, is ordered alongside it. Waiting is registered through CatchTable, and inside the shop customers order and pay at a kiosk, then pick up the food themselves. Wait times run from around two hours up to four hours.
