The novelty is fun, but it can wear off quickly. If you're easily amused like I am, you may enjoy M&M World. Even if it's just awe at the sheer number of products that can be branded with cartoon candies.
The best part is the wall of M&Ms, all kinds of colors and flavors.....teal, chartreuse, fuschia, peach, peanut butter, dark chocolate, giant shrek M&Ms....whatever combination your twisted heart could desire. Not bad for snacking on the drive back to LA after a debauched weekend in Vegas.
