"A Sandwich to Be Reckoned With There are more complex items in Vietnam's culinary arsenal, but for sheer, simple enjoyment few things beat the humble banh mi. A filled baguette stuffed with all variety of goodies from grilled pork to pickled daikon and tasty pate, the sandwich has transcended its origins to become one of the country's greatest food exports. Purists would argue that the best versions can be found in the central regions (and particularly in Hoi An), but Hanoi has some sterling choices, too, such as Banh My Thien Su, which offers some of the most generously stuffed baguettes in the city."
