I'm a little mystified as to why someone would want to hang out in a bar that was so cold you had to wear a parka, but there's now a minus5 bar at the Mandalay Bay hotel. Here's the official site for minus5, which has a few more international locations. And here's Richard Abowitz describing a visit to the bar. Funniest line "it was not that crowded while I was there, and it was easy to explore without a wait to get inside."
Here's video of some amusing dancing at the minus5 bar in Vegas:
