It's great food, much better than the average Chinese restaurant of the Phoenix area. The only one in Arizona that is better is Lucky's in Tucson, but that's as much for location and atmosphere as it is for food.
The other commenter about the "soup nazi" staff was right on, and I was so amused by this that I will go back again and again. I had my order in a message on my phone. I was looking at my phone when I was ordering at the counter. She told me I was too busy... that I shouldn't be texting... I tried really hard not to laugh, because she was dead serious. It nearly took me back to the 1970s and Goff's restaurant in Dallas.
Four stars for the Snow Hill Chicken and an extra star for the admonition over "texting".
