Muslim noodle restaurants are ubiquitous all over China, but Xi'an, with its large Muslim population, has a far better class of them. Most restaurants have photos of the various dishes on the wall, and all you have to do is point. My personal favorite is 面片, which translates as "noodle flakes." The chef has a clump of dough and flicks thin slices of noodle off into boiling water. At Lanzhou Muslim Traditional Beef Stretched Noodles I like the noodle flakes with beef and potato gravy, but the options for toppings are endless.
