Markthalle Pfefferberg, the 700-square-meter hall of shops and food stands, is a fun stop on any tour of the restaurant-packed Prenzlauer Berg neighborhood. If you only try one place inside, make it Taquería el Oso, which serves juicy al pastor tacos sliced straight from the trompo. Tables can be tough to come by on weekend afternoons and evenings, so plan on showing up around noon when the party people are still sleeping in. And if you want to try their birria, make sure you come on a Sunday.
