Terraces of tortillas tower over simmering mole, a special recipe that has been passed down for three generations, on tables in the 15-year-old eatery with a family atmosphere. Here, in Blue Iguana's kitchens, Chef Castillo imparts the culinary arts of the Aztec empire to his team of cooks using his knowledge of Chihuahua, Mexico. In this province, families fiercely guard such traditions to honor their forebears and preserve their culture's legacy for future generations. Castillo specializes in mole recipes, which teem with rich ingredients such as chocolate, almonds, and pumpkin seeds. Guests seeking a lighter meal can customize tacos with a choice of more than 10 fillings, including grilled yellowfin, charbroiled sirloin, sautéed mushrooms, and spicy pork chorizo. The margaritas are mixed with the restaurant's brimming top-shelf tequilas such as Patron Silver and Don Julio. Diners can also visit the Park City location for breakfast dishes.
