Probably the only Chicago landmark that can compete with the Sears Tower, the Billy Goat Tavern is the stuff of legend. Be it the infamy spawned from Saturday Night Live (Who can forget, "Cheezborger, Cheezborger, Cheezborger…"), the glory days of Chicago journalism or that whole Cubs losing-streak voodoo talk, The Billy Goat is a local institution. Tucked in the back of the Jazz Food Court in Terminal One, you'll find the best cheezborgers in the entire airport. Their Italian Beef has turned many an extended layover into an enjoyable--albiet sloppy--culinary retreat.
