When it comes to simple chinese food this is the best I've had in arizona. Their soups are excellent. I am guilty of ordering "americanized" dishes but considering how much better they are than any other place I've tried they must be doing something different than others. My girlfriend has ordered some more "authentic" dishes and been quite happy with them. Overall this place is about as authentic as they come, I find the service great, I think people who aren't used to eating at asian restaurants might not.
Even if the taste doesn't exceed expectations, their prices and portions are absurdly good. Even if you have to pay the $1 extra for lunch specials after 3pm you will still get a huge 2-meals worth portion, with rice, yummy soup and an egroll for under $6.
