Vietnam, as you would expect, has a huge number of different kinds of noodles.
If you want to try the regional Hoi An variety, then you need to try Cao Lau which are brown rice noodles that are mixed with lye water.
This is ash from the lye that comes from the wood on the Cham Islands which are around 12 kilometers from the coast of Hoi An.
The noodles are hand cut and then topped with pork, rice crackers and fresh herbs, all soaked in a delicious meat broth.
One of the best places to try the noodles is at Cam Ga Huong which is located off Le Loi Street.
