"Xoco is from the same team as Frontera Grill, and located right next door in River North. Well, it's also located in Terminals 1, 3, and 5 at O'Hare, but this is the one we're going with. Xoco specializes in delicious tortas, like the ahogado made with carnitas, black beans, and pickled onions submerged in a tomato-arbol chile broth, or the pepito that has short ribs with caramelized onion. It's one of our favorite spots for an affordable lunch in the neighborhood." - sam faye, adrian kane, john ringor, nick allen
