I've been sad for a long time that I've been unable to find acceptable yang rou chuan or lamb kebabs in Los Angeles. The Northern Chinese Restaurant did have some on the menu, but they weren't very good. I was recently driving on valley blvd, however, and came across a sign advertising yang rou chuan. I went inside the restaurant, ordered them, and they turned out pretty good. For those of you looking for other Uyghur dishes I'm afraid I have to disappoint you; the restaurant didn't have any. It seemed to be of the Beijing/Tianjin style. Anyway, if I remember right the restaurant is called 818 shaokao and it's a block or two east of San Gabriel on Valley Blvd.
