Celebrity chef Rick Bayless has opened a unit of his Tortas Frontera restaurant concept at the University of Pennsylvania. The menu features tortas, griddle-baked Mexican sandwiches filled with various meats, cheeses, vegetables and condiments, along with cazuelas (variously topped rice bowls), caldos (Mexican soups), molletes (Mexican flatbreads) and a guacamole bar. There are also various salads and all-day Mexican flavored breakfast choices.

Located in the ARCH (Arts Research & Culture House) building, it is open seven days a week. Other Tortas Frontera units are located at Chicago's O'Hare International Airport and in the Urban Market at Chase Tower in Chicago's Loop.

Dining at University of Pennsylvania is operated by Bon Appetit Management Co., which worked with Bayless on deploying the concept, the first Tortas Frontera in a college location.
