Bánh Mỳ Thủy sells traditional bánh mì across from Dong Xuan Market in Hanoi. The sandwiches use thin bread with pork liver pâté, cilantro, cucumber, and a house-made chili sauce. It operates separate morning and afternoon hours, with a few chairs set out on the street, and takeout is available. The bread is cold and small, and the fillings are modest.
