From what I hear, this is the oldest continually operating restaurant in Phoenix, and is also the last remnant of Chinatown. The place is old and run down, parking is a pain, and it's tough to get to sometimes because of what seems like never-ending construction and road work.
But...the food is outstanding! I am eating my way through the menu, and everything I have tried is fantastic and hot and fresh. It's Cantonese, so a bit different than some folks may be used to unless they came here from a city with a big Chinese population. The service is great too!
