Cristina Martínez's James Beard-winning taqueria in the Italian Market has one thing on its mind: lamb barbacoa. The menu is tight by design, built around slow-cooked lamb piled onto house-made tortillas with cilantro, onion, and a bowl of consommé on the side. The room is festive and casual, and the crowd tends to be a mix of South Philly regulars and people who drove across the city specifically for this.
