If there was one dish that Hoi An is known for, that would undoubtedly be a steaming bowl of cao lau. The signature dish uses locally grown rice noodles as the primary ingredient, which is mixed with thinly sliced roasted pork and a few other sub-ingredients such as green sprouts, croutons, peanuts, rice crackers, scallions, lime, chilli jam and local herbs and fresh greens. While some claim the dish has its roots embedded in Chinese cuisine, the origin of the dish is not quite clear. However, if you are craving a steaming bowl of cao lau, you'll have to hop on a plane to Hoi An, as it is the only place on earth where you'll find cao lau.
