This humble restaurant is usually crammed with students, professors, and working stiffs who come for the generous portions of Vietnamese classics. The Foyer is also a nonprofit dedicated to all things Vietnam, so you can enjoy art and seminars after you slurp your steaming bowl of pho (meat broth with vermicelli and vegetables) or bò bún (8€), a heap of rice vermicelli with sliced beef and a delicious tangy sauce. Finish with a Vietnamese cà phê, a drip coffee—the beans are roasted with butter and rum, giving it an exquisite flavor.
