Cheonsa Jogae Gui Unlimited Refill is a shellfish grill restaurant in Gyodong, Gangneung. For an hour and a half, diners eat grilled shellfish with unlimited refills, and can add ramyeon or kalguksu at the end. The clams and scallops are large, and one pen shell and one hard clam are served per person at the start. Because grilling shellfish produces smoke and heat, the room can stay hot even with the door open and the air conditioner on.
