Hanoi and Saigon have landed in a chic little red Vietnamese restaurant in Mitte. There are only five dishes and two daily specials, but they're so delicious you'll be ordering a second bowl of rice to soak up the leftover sauce. After your gói bo, try some jasmin or artichoke tea. You'll have to fight the über-cool crowds for a table as Mr. Vuong doesn't take reservations.
