Fun place to take the family and a great way to beat the Vegas heat for an hour or so (especially if you combo this visit with a visit to the M&M store next door).
A lot of fun stuff to look at (I had no real interest in buying anything here, but other family members did). There's a polar bear you can take a picture with downstairs (Why? I'm not sure). We bought the cola sampler. $7 for 16 cola flavors from around the world. Plenty for the 6 of us to share. Family had a lot of laughs trying some of these "unique" tastes - beware of the mouthwash flavored cola!
All in all, it was a fun family outing.
