The Differences Between Ice Cream and Gelato

There are over 37,000 gelateria in Italy apparently. All of them are fresh and as Alfios says, if there is leftover gelato and they're trying to serve it to you the next day, bad gelateria do not go there. The big differences are the amount of air, milk versus cream and the temperature it served at. Ice cream has a lot more air in it, up to 50% more air than gelato.
