Haiphong has a very authentic cuisine with its dishes exhibiting the perfect medley of spicy, sour and sweet. Haiphong, being a port, serves particularly exquisite seafood. Some dishes such as field crab red noodle soup, crab spring rolls, field crab hot pot, sautÚd snail, Hai Phong spicy sandwich are native to Haiphong and have spread to many parts of Vietnam. However, some foods such as Cat Hai fish sauce (made from fresh Cat Hai fish from the Gulf of Tonkin and served with crab spring roll), Haiphong dried noodle (used to make crab red noodle soup) can be found only in Haiphong. The must-try foods here include square crab spring roll and red crab noodle soup.
