Casa Dani

One of the most famous stalls at Madrid’s Mercado de la Paz is Casa Dani, a spot that serves up generous portions of croquetas, oxtail, and their famous tortilla de patata. What makes this version so great is that they fry the potatoes in sunflower oil—this helps them retain their original, sour flavor, which is then complemented by the sweetness of the onion. This tortilla can be anything you want it to be—breakfast, lunch, dinner, a snack, or a really epic hangover cure.

The menu del día is only €15 and gets you an appetizer, main, dessert, and coffee—expect things like tomato soup from Andalusia called salmorejo, lentil soup, pork chops, and fish from the market’s vendors.
