Pure is the currently the hottest club in Las Vegas. Its popularity can be attributed to a large terrace over looking the Strip. It's super crowded and fairly difficult to get in. Just dress cute and have girls in your party.
There are a couple of ways you can beat the long lines:
1. There is a ladies-only line on the left side, facing the club entrance. The times that I have been, ladies are able to get in without cover, no hassles, or lines by queuing up.
2. You can go to the Pussycat Dolls Lounge next door, which is also connected to Pure. Entrance to Pussycat Dolls Lounge is effortless, and starting the night off there is a good idea, especially because you can migrate over to Pure after 10 or 11pm, when the club actually opens.
Those who like to follow current party/club scenes must check out Pure. It's rather crowded, but a great place to people-watch and meet strangers.
