Carrer del Poeta Cabanyes, 25, 08004 Barcelona, Spain
Forget Google Maps: You’ll quickly locate this venerable tapas bar in El Poble-Sec by the line out the door. With standing-room-only space for just 20 people, this sliver of a spot fills up fast—and stays that way until closing time. In a room lined floor-to-ceiling with bottles of wine, liquor, and pricey vinegar, you can sample a dizzying variety of tapas and montaditos (small bites served atop slices of bread). Many of the ingredients—namely the mussels, sardines, and tuna—come from cans, which sounds suspect, but Spanish conservas (tinned food) is actually of the highest quality. The cheeses—all fresh—are also top-notch.
