Gaeseong Sangin is a charcoal grill restaurant in the university district near Pusan National University in Busan. It serves all-you-can-eat samgyeopsal, pork jowl, and pork collar, and the house style is to eat the meat together with grilled bean sprouts. Tables are close together and nearby conversations carry, because the restaurant draws a large crowd. Ventilation is poor and the room feels stuffy.
