"Sprawling a full city block with more than a football field's worth of bustling stalls, Mercado de Maravillas is the largest municipal market in Europe and the destination local chefs and adventurous cooks descend upon in droves to source hard-to-find ingredients. Its far-flung location in Tetuán, three miles north of the city center, keeps all but the most intrepid tourists at bay, guaranteeing the true-blue Madrileño experience that other markets lack. Don't leave without a sachet of hand-plucked saffron from La Mancha at Casa Serrano, for making heavenly fragrant paellas back at home." - Benjamin Kemper
