Check out the Japanese noodle shop in the rear of Tensuke Japanese Market in Kenny Center. Just like the modren noodle shops where I used to have lunch in Tokyo when I lived there a few years ago. I tried the miso ramen, $6.50, very good and completely authentic. Many other typical, reasonably priced soba and udon bowls. You can also bring in the sushi you get from another window in the market.
