Xiaoyun Road is located between Sanyuan East Bridge on the Third Ring Road and Xiaoyun Bridge on the Fourth Ring Road. This is a long street from southwest to northeast. This kind of oblique street is rare in Beijing and belongs to an important traffic artery between the East Third Ring Road and the East Fourth Ring Road. There are many office buildings on both sides of the road, such as Jingxin Building, Modern Shi Sheng Building, Pengrun Building, Datong Building, Air China Building and Jingrunshui Garden Villa. Such a commercial place and bustling place are of course full of restaurants of various grades and tastes, most of which are exotic. It is these exotic flavors, with their unique elegance and charming taste, that create the petty bourgeoisie sentiment of Xiaoyunlu. On Xiaoyun Road, there are many famous restaurants, but they are not too large in scale and are famous for their emotional appeal. For example, Lugang town, lemon leaves with Thai flavor, Faust who manages romantic French cuisine and so on are all rumored by petty bourgeoisie.
