Las Vegas StripBurger has the water misters turned on. It actually looks pretty cool at night, seeing the thin haze of water mist changing colors with the lighting at StripBurger.
The Boardwalk had a nice water misting system in front. I think the Harley Davidson Cafe has water misters. Some vendors at The Hawaiian Marketplace have rigged up fans that blow water mists horizontally, but it's not the same.
Water misting seems to be a luxury done by smaller places. Like StripBurger; a smaller place with attention to detail. Colorful lighting, water misting, atmosphere, a menu with a focus, and attention to details.
StripBurger is located on Las Vegas Boulevard, across from the main gate of Wynn.
