Burger Ok Jongno is a hamburger restaurant next to Burger King across from Tapgol Park in Jongno 3-ga, Seoul, selling Korean-style burgers and sets. It uses double patties and large buns, and the flavor brings sanjeok to mind. Orders are placed at a kiosk on the first floor, with ample seating on the second and third floors and a view of Jongno through the full-length windows. The patties include some tough parts and the sauce is sparse.
