Talk about mixed use! The Port Authority Bus Terminal has 250,000 people passing through it daily. It has the highest grossing Cinnabon franchise in the country. On top of this commuter machine, put a Cirque du Soleil theater, a theme restaurant, a golf driving range, a 600 room timeshare hotel, and don't forget, an interactive aquarium. The sharks in the tanks can check out the sharks on 42nd Street!
