This is one of those places that is basically overrated just because of its location and longevity. There are so few places that have survived in the downtown Phoenix area for as long as China Chili has, and for that, it probably does deserve a lot of credit.
That being said, it's basically an average Chinese restauant. Comfortable, convenient, clean, and it offers all the standard fare. It's everything you'll need for a weekday dinner, but not much more.
Try the sizzling rice soup. It's very good. Plus Jerry Colangelo is known to take out their sweet 'n' sour shrimp...or is it the chicken? Who cares, either way, that's pretty cool.
