Taco de Bistec at El Tragón Taqueria

With its crispy griddled cheese crust, the costra taco is a product of Mexico City that’s becoming popular in the States. You’ll find a really good version at El Tragón Taqueria, which opened last October in a gas station complex near Halsted and Division. Listed on the menu as a taco de bistec, it comes with seared green onions and a cheesy Chihuahua crust that amalgamates with tender slices of rib eye. $4. 1234 N. Halsted St., Goose Island
