The 12 Best Tapas Spots In Madrid - Madrid - The Infatuation

"Juana La Loca checks all the boxes of a perfect tortilla de patata—it's loaded with caramelized onions, and the egg is never overcooked, but not so drippy it feels raw. This tortilla is why everyone flocks to this trendy, always-packed neighborhood joint, especially on Sundays when friends meet up with friends for a ceremonial La Latina beer and tapas bar crawl. Definitely make a reservation for both the roomier seated section or try your luck walking into the standing area in the bar (just expect to go shoulder-to-shoulder with other diners)." - lori zaino
