Mercado de San Miguel

"Get a real taste for the diversity of Spanish cuisine at Mercado de San Miguel, an always-happening food hall in a historic ironwork building. Instead of committing to one restaurant, you can sample from more than two dozen—a key reason why the market is a draw with both tourists and locals. Although prices are high, many vendors offer free samples. Try the banderillas (skewers of olives, veggies, and seafood) for about 1 or 2 euros apiece." - Ramsey Qubein
