Cao Lau is a must-try specialty of Hoi An, made from noodles, pork, and distinctive regional greens. The dish is said to derive from various culinary influences, featuring thick, chewy noodles that are quite unlike any other in Vietnam, owing to being prepared with unique water from ancient Cham wells and lye of a specific kind of ash. Topped with slices of juicy barbequed pork, fresh lettuce, bean sprouts, and crispy croutons, Cao Lau offers a delightful mix of textures and tastes. Near Vincom Plaza, numerous eateries serve this famed dish, each with its spin but consistently delivering a taste that's true to its cultural heritage.
