1.
Turn left at the first crossing on the north side of New Oriental Building and go straight to the chart (longest 10 minute). Looking to the left, there are a bunch of Donglaishun, KFC and monk source houses. I recommend "Qiaoxiangyuan Crossing the Bridge Rice Noodles", which is the most authentic branch in Kunming, Yunnan. I have been to Kunming head office, and I feel that the taste here is no problem, but it is a little more expensive than there.
2.
There is "real kung fu" on the fifth floor of Dinghao, which is quite good and distinctive. There are also many brands like Yoshinoya, DQ, KFC and Master Kong.
3.
If you want to buy something, there are several specialty stores on Zhongguancun Pedestrian Street and anime shop.
Xinhua tong, Jin lehui and so on have all been said upstairs.
4.
If you want to eat roasted wings, I know another one, which is closer than Ximen roasted wings. Or take the first crossing in the north of New Oriental Building, turn left to the east, cross the street and go straight. There are already many snack bars on the left side of the road, and there is also a shop that looks like bamboo, with good cold noodles, meat buns and kebabs. If you walk for about a quarter of an hour, it is called "Wing Cool" on the left hand side of the road.
