Juana La Loca is a stylish, popular restaurant with glass cases sitting on the bar filled with tapas and pintxos. Deciding on what to order feels like the tapas version of Tinder, only unlike Tinder, every single option at Juana is actually appealing—especially their famous tortilla de patata, a dripping egg and potato dish loaded with caramelized onions. It’s always packed, so definitely make a reservation, especially if you want to eat here on Sundays. That’s when locals head to the La Latina neighborhood to roam around, drink beers with friends, and tapas bar hop.
