"Unlicensed food stalls, which provided cheap everyday food such as congee, rice and noodles to the general public of humble income,
appeared in as early as the late 19th century in Hong Kong. The stalls could be found not only in Central,
but also in Wanchai and the peripheries of Happy Valley Racecourse around Wong Nai Chung Road.
Since 1975, many dai pai dongs have been moved into temporary markets...the government began to buy back "big licences" from the licence-holders in 1983.
Since most of the licensees were aged, and the licenses are only legally transferable to their spouses, many of the licensees were willing to return their licenses for compensation.
Since then, the number of traditional dai pai dongs has declined rapidly.
In May 2005, the existence of dai pai dong in Hong Kong caught considerable public attention,
as Man Yuen Noodles, a renowned dai pai dong selling noodles in Central,
faced imminent closure due to the death of the licensee.
The news came after the closure of a bakery famous for its egg tarts, also located in Central and forced to close because of the rise of rent"

The space on the left is once the site of the Man Yuen Noodles. Its neighboring dai pai dong is still in business...but for how long?
