Patatas Bravas is a classic Spanish tapa that is a favorite among locals and tourists alike. It consists of crispy fried potatoes that are served with a spicy tomato sauce and a creamy aioli. The potatoes are typically cut into bite-sized pieces and fried until golden brown and crispy. The spicy tomato sauce adds a kick of flavor, while the aioli provides a creamy and tangy contrast. Patatas Bravas can be found in many bars and restaurants in Madrid, including those near the Royal Palace.
