Banh Mi Duc Long is a local restaurant in a quiet alley of Hanoi's Old Quarter that serves egg banh mi and vegetable banh mi. Charcoal-grilled bun cha is cooked right next door, and egg coffee and fruit juice are also served. When ordering, staff ask about spice level first and adjust it to the request. There are seats to eat in, and guests come for coffee with their first meal of the morning.
