It's really not worth spending ten yuan to buy a few slices of mutton, which is not as real as eating a bowl of ordinary mutton bubble and spending 7 yuan to buy a Chinese hamburger.
Moreover, there are many snacks similar to dough in Xi 'an, and there are many ways to eat them. The eating methods and tastes of rolled dough, steamed dough and baked dough are different, and there are rice skin, cold noodles, stuffed dough, bean jelly, etc. It is difficult for even locals in Xi 'an to distinguish them clearly.
Therefore, foreign tourists must distinguish what kind of dough they come up with when traveling, so as to prevent cold rice noodles from being ordered when eating, and rice skin is indeed served before the table.
In short, you should do enough strategies before traveling to Xi 'an to prevent you from encountering various routines and making yourself suffer losses.
