The most apt description we've found of Chicago's O'Hare Airport is a Foursquare review that simply states, "Four words: automated toilet seat covers. Two more words: Garrett Popcorn." O'Hare has undergone massive renovations throughout the years and is now one of the most bustling, restaurant-speckled, shopping-laden international airports in the world. With 182 gates, moving sidewalks, and yes, rotating toilet seat covers, this massive facility was once the busiest airport in the world. In light of such heavy traffic, it's no wonder the facility has built in so many things to do - the United Airlines terminal even has a (fake) dinosaur.
