A requisite when visiting Oaxaca is a trip to the picturesque Mercado 20 de Noviembre. At the renowned Pasillo de Humo, the smoky aroma of grilling meat wafts right out to the street luring customers in. Order from a selection of meats on display at any of the Carne Asada vendors. Your selection is then grilled and served with radishes, onions, chilies, salsa, and freshly made tortillas.
