Tortas Frontera by Rick Bayless

If you have to eat at O'Hare, Tortas Fronteras is one of the best spots to grab a meal. Luckily, it's located in three terminals (sorry Terminal 2). Each torta is made-to-order and comes with crackly bread and tasty fillings like roasted chicken with poblano rajas, chile-rubbed cauliflower, and even chorizo and egg for breakfast.

Located in:

Terminal 1, near Gate B10

Terminal 3, near Gate K4

Terminal 5, near Gate M18
