In a city teeming with markets, this is one of the capital’s only true farmers’ markets. Everything is grown and produced within 100 yards of the city limits. It takes place at the corner of a park in the Roma neighborhood, and wooden benches are set up so that visitors can enjoy mushroom tamales, hippie-style tacos filled with cactus and wheat berry salad, and refreshing ices in flavors like cardamom or cucumber lime. Don’t miss the booth that sells one of my favorite mezcals. It's made in the state of Guerrero, and at the market, vendors funnel the liquor from huge vats into beer bottles decorated with colored straw and papier mâché animals.
