Yukgak Gogi is a grill restaurant on the 10th-floor rooftop of the Seoul Express Bus Terminal, serving ogyeopsal, pork collar and pork jowl. It uses outdoor seating, with tables where diners look out at the sky and Namsan Tower while they eat. Side dishes are self-serve, and because the space is small you should call ahead to check whether a reservation is possible if you want to wait less. The tables are close together, so you sit snugly against other diners.
