Leave it to a city known for its financial prowess to come up with a bar like this. The Exchange Bar & Grill puts the economic principles of supply and demand front-and-center in a way we've never seen before. Thanks to unique, fully-automated drink market software, the prices of drinks rise the more they're ordered and fall when they're not, letting you watch the ticker above the bar to pick just the right time to place your order. Oh, and be sure to keep your eyes open for the Market Crash, when everything hits rock-bottom pricing. They also offer a menu of tasty bar food and plenty of TVs for watching the big game, if you can take your eyes off the ticker, that is. [via]
