烟袋斜街

This is one of the most famous Hutong street in Beijing, had a great foot massage here, one of the best I tried, done by a 52 y/o uncle.

Some illustration about 'Hutong':

"People say that the real culture of Beijing is "the culture of hutong" and "the culture of courtyard". How true that is. Often, it is Beijing's winding hutongs that attract tourists from home and abroad rather than the high-rise buildings and large mansions.
Hutong is a typical lane or small street in Beijing that originated during the Yuan Dynasty (1271-1368). "Hutong" is a Mongolian word, meaning "water well". During that time, water well is the settlement around which people lived. There are tens of thousands of hutongs surrounding the Forbidden City. In the past, Beijing was composed of countless courtyards. Hutongs were formed when people left a passageway between two courtyards to make entering them more convenient.
As the symbol of Beijing City, a hutong has its own layout and structure, which makes it a wonder in the world. When taking a bird's eye view of Beijing, you will find the combination of hutongs and courtyards just like an orderly chessboard with delicate gardens, fine rockeries, and ancient ruins. Hutongs have witnessed the development of Beijing. Where there is a hutong, there is a story."
