Kkuldwaeji Munhyeon Gopchang is near Sasang Station in Busan and serves pork gopchang (grilled intestines) and pork skin. The gopchang is pre-grilled so the outside is crisp and the inside stays moist, then finished briefly on the table grill. Ordering gonggibap brings a doenjang jjigae, which is refilled for free. The restroom is outside the store and small.
