El Xampanyet

In the tourist-heavy, chronically overpriced El Born neighborhood, there aren’t a lot of bars like El Xampanyet left. Open for close to 100 years, it stays so busy that the scene often spills out onto the street, where locals happily mingle with out-of-towners. And a glass of cava will only set you back €2.

The baked potato is topped with tangy sobrassada and an aioli so garlicky you may worry nobody will want to speak to you after eating it, but it tastes so good you won’t care. This place is always packed, so get there just before they open at noon, and again at 7pm, to beat the crowds.
