Of all the great street food in Hanoi, perhaps there'd be no greater crime than to leave without having had Bún chả. Bún chả Hà Nội (grilled pork vermicelli soup) may not sound particularly appetizing, but be assured this thin rice vermicelli served cold with grilled marinated pork is legendary. Bun cha is served with a plate of white rice noodle (bún), a steamy broth and herbs. Traditionally, chả (the pork) is a marinated pork patty, but another type of chả (small pieces of fatty pork belly) also often accompany the patties. Learning the top Bún chả joints is a right of passage for all Hanoi residents.
