Mercado de la Paz is a local treasure, filled with fresh produce, meats, seafood, and a variety of small spots where you can enjoy a drink or a bite. It's not touristy at all, making it a true Madrid experience. I love stopping by Casa Dani for their famous tortilla, which many say is the best in the city. Whether you're shopping or just relaxing with a beer or wine, this market has a cozy, authentic vibe.
