Finding any quality Japanese restaurant in the Phoenix metro area is a challenge in and of itself, so despite inexplicably being a combo Italian restaurant, I will be returning.
First; parking. I will not say anything that has not already been said. It's tiny, it's cramped, it's like trying to find a seat in my apartment when I have friends over. Get there early or park on the street.
I ordered the spicy ramen, which is not very spicy, even for a wuss like me. Lots of noodles, a tasty broth, solid if unspectacular ramen. I also got the tempura shrimp roll, which while surprisingly thin on the rice, was still decent enough.
Service was a little lacking, but the joint was jumping so it's forgiven.
