The Exchange Bar and Grill located in New York City has come up with one of the greatest gimmicks of all time, and it will probably work too.

The prices for its food and drink will be dependent on market demand, meaning that if a lot of people are ordering the Tuna Melt Grilled Cheese Tilapia Sanswich, its price will be lower. If only a couple of patrons at the Exchange Bar and Grill are ordering it, then it will be more expensive. Same goes for beer too!
