I happen to like shoyu ramen but the question came about because one of my kids has a friend going to Tokyo and asked me. Shouldn't have to be limited to Ebisu. I'd say that traditional ramen (for a first-time visitor) is either miso or shoyu and has round noodles. I'd even argue that traditional would have to include char-siu (however it is pronounced).
Now I can just reference them to this thread, thanks!
