As the name implies, Ayu Ramen specializes in noodles with grilled ayu (sweetfish), served in a lightly flavored soup so as not to overpower the delicate ayu taste. You can order a yaki-onigiri rice ball to soak up the flavors of any remaining soup. In the summertime they're also open for lunch from 11:45am-3pm, or until their soup runs out.
