La Pepita is a small and enormously popular sandwich and pintxos bar in Gràcia that makes its own bread, sources its ingredients carefully, and produces combinations — cured meats, roasted vegetables, excellent cheeses, house-made sauces — that are significantly better than the word "sandwich" suggests.
The room is attractive (mismatched vintage furniture, plants, good light) and the service is friendly. The neighbourhood crowd that uses it daily is the best indicator of its quality. Book ahead for dinner; lunch is walk-in only.
