The iconic M&M store on the Vegas strip is as ever changing as it is expansive. There are 4 floors of food, fun, characters, and clothing. You can find anything from plain M&M's to mugs, clothing for everyone 0-100 yrs, and home accessories. You name it and they literally have it.
It's centrally located,or what used to be central, on Las Vegas Blvd, near the MGM hotel block. It's literally packed with people! The second floor is the candy store with candy from wall to wall. This is the location where you will see people from all over the world.
If you see the M&M wall just ask an associate for a free taste.
Do yourself a favor and check out this 4 floors of goodness. You can even have your name printed on your purchase.
It's a tourist trap, in all honesty, but a rather fun one.
