Idongju's Burning Gopchang is a direct-fire grill restaurant in Busan that serves gopchang, makchang, and doraechang. The gopchang is cooked over fire with a lightly spicy seasoning, and the doraechang is served alongside it. The makchang is tender rather than chewy, which leads customers to order more of it. The vegetable gopchang is seasoned with more salt than sweetness.
