There are many restaurants outside the south gate of Tsinghua, from east to west: two instant-boiled mutton, an old Beijing Zhajiang Noodles Pavilion, and then a fairy forest, which is also very distinctive and suitable for young people to go. You can eat in a hanging chair. Generally, it is more suitable for chatting and drinking here. It's not suitable for a proper meal, and the consumption is OK. I ordered two packages, two cups of freshly squeezed juice, and always ***5 yuan. There are several more to the west, but I haven't been there. You can go and see for yourself. Also, after coming out of the south gate of Tsinghua, cross the overpass and walk eastward. There are McDonald's, KFC, Yonghe Dawang, Pizza Hut, LG, and Pizza Hut. Anyway, there are plenty of places to eat. Just now, someone said that Yunnan restaurant seems to be near Minzu University, a little far from Tsinghua and Peking University, but it is quite distinctive, where bamboo shoots are particularly delicious.
