I am a ramen person, I love ramen and whenever I visit Japan, I eat tons of ramen. And I do believe this is the best ramen you can get in the state of Arizona.
If you don't mind to drive a bit to try some better one, visit Mitsuwa in Torrance, CA, you won't be disappointed.
If you don't mind to fly to Japan, go to Shin-Yokohama Ramen Museum in Japan, it is a under ground ramen heaven place.
