My friend ordered this famous Laos noodles soup. He said ‘ If you visit Luang Prabang, you must eat Khao Soy.’ I tasted some. It was amazingly delicious. Sauce of ground pork and tomato layered on top pork broth. The soup is a fairly simple pork broth with medium wide rice noodles. The highlight is the pork tomato sauce that’s poured on top of the bowl. And it’s accompanied by fresh watercress leaves to balance the heaviness of the pork sauce.
