What can I say about Chou's that hasn't been said already? The only good authentic Chinese food in the Chandler area. I come from the San Gabriel Valley where good Chinese food is on every street corner. Chou's is still one of the better places I've tried.
Get the pork pies (beef is a little less juicy but still good), beef noodle soup, dumplings (pro tip: you can get frozen ones for home. Fill a medium pot halfway with cold water, put in frozen dumplings, bring to a boil, put a large mug of cold water in, wait for it to boil again and they are done), lamb skewers, and water boiled beef/fish (extremely spicy).
If you're tired of eating Kung pao chicken and beef and broccoli all the time, stop by here. You'll be pleasantly surprised.
