After visiting this store many years ago.......I must be getting old, because I don't remember this store to be (4 levels) of M&M's themed stuff.
I'm sure if you have kids, this place would be really neat for them to visit, as the beautiful colors of the M&M candies display would quickly get their attention!
I would say the M&M's World, is just like the Hershey's Chocolate World store..........lots of M&M themed merchandise, as well as candies.......just another tourist trap.
I wished this this store had some history or facts about how this wonderful candy came about........but apparently, it's just a store built to sell their wonderful candies, & M&M merchandise.
