First of all, I suggest you go to the "Xinzhongguan Building", where there are many restaurants to choose from. For example, Dadong Roast Duck Restaurant, a well-known brand in Beijing, can enjoy the unique quadrangle architectural style in Beijing while tasting authentic Beijing roast duck. In addition, there are many Korean food, Japanese food, western food and other restaurants, which you can choose according to your personal taste.
If you want to be more local, you can also try to go to the snack street to taste the local night market snacks. Go west from Xinzhongguan Building, cross the underground passage of Metro Line 2 station, and you will see a snack street. There are all kinds of snacks here, such as barbecue, kebabs, pancakes, mala Tang and so on. And the price is relatively close to the people, which is very suitable for a group of friends to eat midnight snack.
Finally, there is another choice different from restaurants and snack streets-night market. A few minutes' walk to the west from Xinzhongguan Mansion can see a "ghost market", where there are many stalls selling all kinds of goods, snacks and games at night, which is very suitable for tourists who want to experience the local nightlife.
Generally speaking, if you want to find supper near Xizhimenwai Street in Beijing, there is no need to worry. Here, you can taste special snacks and restaurant food different from other places, and enjoy a night view and cultural atmosphere different from that in the daytime.
