Two American tourists, who met by chance on a bus from Sa Pa, enjoy banh mi and beer in downtown Hanoi.
Vietnam's popular banh mi have been several times honored among world's best sandwiches by international media.
The classic version combines cold cuts with vegetables such as coriander, cucumber, pickled carrots and daikon, along with French-style condiments including pâté and mayonnaise.
Other popular fillings include cha lua (Vietnamese pork bologna), fried eggs, grilled pork and meatballs.
