I would suggest staying in the airport.. It's expensive to take a taxi and not really worth it. I would not suggest going downtown because there might be traffic. Everything local is average. I would suggest you either eat at Wolfgang Pucks in the airport or at the Billy Goat Tavern. The Billy Goat is a branch of Chicago's restaurant associated with there baseball teams curse. It later received attention on the Cheeseburger Cheeseburger skit on SNL. However, the food is not as good as the original Tavern. Though you are eating average food, you didnt have to kill yourself to get it. Airports have bars and bookstores for a reason.
