There is a non-descript ramen shop about 75 meters from JR Torisawa Station called Kiraku that specializes in cha-shu pork. The thick chunks are extremely tasty and amazingly tender. The ramen and fried rice is competent but nothing special. The cha-shu pork is special. Japanese Gourmet Navi entry is here. The google maps street view is here and it is up this street on the right side.
