Gyoku (the on-yomi for "tama", as in "tama negi", see their logo?) is another winner for tonkotsu gyokai in the fair state of Kanagawa-ken. Richer taste than most, and the pork was grilled on the outside and cut more thickly, and had less fat. The noodles are made in-store. Excellent. Not much more to write here. You can take a bus east from the bus stop locations on the southeast side of Kawasaki Station to get to the area quite easily, about 7 mins.
