Had Lan Zhou Beef Noodle Soup while living in Anshan, Liaoning, China. This is a recreation with the help of the Zaar Community BB in trying to get it right. It's not exact but close enough for government work. Still makes a tasty soup though. The broth will be full of sliced onions and garlic which the original did not have but I happen to like onions and garlic. You make discard them if you wish. The noodles used in this dish in Lanzhou, Gansu, China would be the pulled wheat noodles which are hard to find in the west but I have seen Lanzhou style dried noodles in Asian grocery stores but I found that using the rice noodles was alot quicker and easier to find.
