Yaowarat Road in Samphanthawong District is the main artery of Bangkok's Chinatown. Modern Chinatown now covers a large area around Yaowarat and Charoen Krung Road. It has been the main centre for trading by the Chinese community since they moved from their old site some 200 years ago to make way for the construction of Wat Phra Kaew, the Grand Palace. Nearby is the Phahurat or Little India. The area is bordered by the Chao Phraya River from the west to the south. Yaowarat Road is well known for its variety of foodstuffs, and at night turns into a large "food street" that draws tourists and locals from all over the city.
