4 floors of anything you could ever want M&M's themed from kids wear, aprons, t-shirt, pj's, key chains to prepackaged fancy containers of M&M's etc. There is also a 20 minute movie in a small theater that you can see and seems to be geared towards children. There is also a photo op with 4 M&M statues.
The major draw is the area where you can mix and match different flavors of M&M's in a bag for $6.99/per pound. Be careful this adds up quickly as I found out. Some of my favorites in my bag included the white cheesecake, original peanut, coffee, regular M&M's, mini M&M's and the mint flavored ones.
We also spent enough to get one of the $5.00 blankets they offer at the register. Worth a stop if you have kids or are just an M&M loving adult!
