Nutella was creaeted by Pietro Ferrero, a pastry maker and founder of Ferrero in the 1940s. During this time, cocoa was in short supply due to World War II rationing. So, to compensate, Ferrero used hazelnuts in his chocolate mix to lengthen his chocolate supply. Nutella is currently sold all around the world and is in such demand that Nutella theft has occurred in places such as Germany and Colombia University.Though Chicago will be the first place to open a Nutella bar in the United States, the idea of Nutella themed restaurants is not unheard of. In fact, a restaurant called Nuttelaria, a Nutella-themed restaurant, opened a couple of years ago in Bologna, Italy and Frankfurt, Germany.
