I am reviewing the dinner not the lunch. As a Hong Kong Chinese, I believe that they probably have the best Hong Kong style Chinese food in the East Valley. All this "moo goo guy pan" stuff isn't real Chinese food so if you expect that, then go to Panda Express but if you know what to order then I think you will enjoy. Yes, there ambiance/customer service sucks but if you went to HK then I think you would be holed in your hotel ordering in because they do the same thing. A better judgment call is to look at all the Asians in there, if you see that then that's probably a better indication; we don't care about anything other than the food. A stronger indication why most Asians don't go to PF Changs etc unless you have a gift card/coupon.
One word of caution, know your Chinese holidays!! If you go during the Mid Autumn festival or Chinese New Year, you will wait for like an hour just to be seated, so arrive early same applies for take-out as well.
