Ogori cafe looks innocuous enough, but holds a surprise in store for its patrons. In a nutshell, you get what the person before you ordered, and the next person gets what you ordered. Thus, if you're in on the game, you can choose to be either a generous benefactor, and treat those that come after you--or try your luck at being cheap. Either way, it's an interesting experiment that explores surprise, kindness and encourages interactions.
