This huge, four-story store on the Vegas strip is dedicated to everyone's favorite candy-coated chocolates. I've never seen so many M&M's in one store, to be honest. From beer mugs with the little mascots emblazoned on them to a display of candies for purchase in every color of the rainbow, this is an M&M heaven. These candies aren't cheap though, so if your kids are craving something sweet, you're going to shell out more than few dollars for a hand-selected variety of chocolate. There's also a 3D or interactive M&Ms movie, but my wife and I decided to pass. It's entertaining, and it definitely belongs on the Vegas Strip.
