If you like spicy food, this is one of the best places in Phoenix to find it. I was taken here by some Taiwanese classmates, and enjoy every trip I make. It's not conveniently located, but worth the trip.
If you can find a Chinese speaking/reading person to bring with you, you will be able to order some of the specials and things that are only written in Mandarin.
There are two menus, the smaller menu with more Americanized fare, and the larger menu with more authentic Chinese cuisine. If you are into the American side of things, their food is what you would expect.
