Bill,
I have only been to Vegas from Salt Lake. However I must suggest that you go visit Coca-Cola World on the strip. I think it is near M&M Land. Coca-Cola World offers a treat called the World Sampler. It is two cafeteria trays full of cups. In these cups are sodas from around the world, and some US flavors of course. It is quite a deal, only 7 bucks!!! My g/f and I tried it, there are a few flavors on there that are a little odd. One from Russia tastes like carbonated rubbing alcohol, but there are A LOT of good tasting ones too. We couldn't finish both trays so we let a few kids have at it.
Gummi Cola...the best candy ever. Soda and candy in one hit.
