In the grand scheme of Phoenix area noodle shops, this place is average. I ordered the spicy tonkatsu soup with chicken for lunch one day this week - it came out piping hot and in a huge bowl. The spice was subtle but definitely present, and the cloudy pork broth had pretty good flavor. The noodles were what was most mediocre in my mind - they were a little chewy and definitely weren't as good as Cherry Blossom Noodle Cafe's. Toppings were light (compared to the picture next to the menu board) but adequate.
I may come back, but for a noodle lunch near work I definitely prefer Khai Hoan.
