If you're really thirsty and want a drink.. this might be one of the cheapest places on the strip to have a quality soda.
There's a bunch of Coke swag (shirts, lunchboxes, pencils) you can buy if you want to advertise for free.. but the best part is the $7 tastes around the world tray. They have 16 sodas from different countries, some really awesome and some downright awful. In addition to this they sell large fountain drinks and floats.
All in all, It's a nice air-conditioned place to take a break from the heat.
