If you choose taxi to get to the downtown area, do remember not to take those which are waiting for hiking in queue, because you should pay more RMB 30 for parking fee as extra.
Do take those taxis who just arrive airport, pay RMB 50 they also willing to take you to city.

It is called Qishan Shaozi Mian in Chinese. Pliable and thin noodle with sour soup and savory minced meat, the feeling couldn't be expressed with words.
The famous restaurant for this noodle is the Yongming Shaozi Noddle Restaurant. And noe it has many branches around Xi'an city. It is very easy for you to find the one near the South Gate.
RMB5 for one bowl.

To me, Niu Du is the most tasty than baked mutton! Nothing could be compared with the sofe and tender meat dipped with seasoning~~~
Just a little more expensive than barbeque. RMB0.3 for one skewer.

If you enter a Kaorou restaurant, you will find or be recommended by waiter one special pie of Hui minority. Captivating appearance (fried golden exterior, but tender interior!!) and cheap.
RMB2 for one plate.

Yes, don't forget to taste Kaorou if you have the chance to visit the Drum Tower and Big Mosque that are close to the Snack Street. And especially in the evening, you will find many foreigners like you there. They are also pulled together by this delicious and cheap food.
