Jinwon Sou Asan Valley is a beef grill restaurant in Dunpo-myeon, Asan. It serves American beef and Iberico chuck flap as all-you-can-eat, with a self-service bar offering paechae, onion, kimchi, ssam vegetables, mashed potato and sweet pumpkin salad. When the meat is finished, diners take their plate to the ordering station and name the cut they want, and adding charcoal raises the heat. Staff responses can be slow at times.
