I was born and raised in the Phoenix area and I always laugh when people make comments about the "quality of Chinese food" here. Are you kidding? At this moment there are more people of Chinese descent in the San Francisco airport than in the entire State of Arizona. You aren't going to find the same food here as you will find in places like San Francisco and Vancouver. It's simply not going to happen.
But, if you've got a taste for Americanized Chinese food, this is a good choice. I'm confused by the ageism demonstrated in some of these reviews. I haven't noticed that a lot of old people eat here, probably because I don't care. Heck, I'd rather be surrounded by people my parent's age than a restaurant full of young children with noodles hanging out of their mouth.
I've always had consistently good service and good food at this restaurant. I'm certain you can find better Chinese food in San Francisco, but Jade Palace is much closer.
