Las Vegas found the formula for nightclub success long ago. The most tried-and-true combinations include a busy Las Vegas Strip location, plenty of party-going clientele nearby, top-notch customer service and enough celebrity appearances to cram the pages of US Weekly.Pure Nightclub at Caesars Palace, though, took those winning elements and threw in a massive multi-room venue befitting of the Roman Empire, a patio with Strip views and its own bar along with the biggest performances found in any nightclub.It's no fluke that Pure Nightclub's winning formula has been the key to its long run. While most clubs are in the midst of a re-branding at this age, Pure Nightclub continues to pack in the crowds and finds lines building up in anticipation of its 10 p.m. opening.Pure Nightclub bathes itself in the universal color for purity, white. The luminous glow fits nicely with the Roman theme at Caesars Palace. Your first few steps inside the club make you feel like you've entered a dream sequence. The illuminated white walls usher you down the main corridor and offer you five options for your night's party.Two entries lead into different parts of the main room. The path directly in front steers you into the midst of the party where a sea of bodies fill the spaces between the bars to the left and right and the stage/VIP seating on the back wall. The second entry on the right leads you to another one of the main room's bars and into a slightly-less crowded area. Now, you might feel compelled to just stay in the main room and with performances by the likes of 50 Cent, B.o.B., Naughty By Nature and more. We wouldn't blame you. But while it is deemed the "main room," there's plenty of other action.An entry on the left of the main hall takes you into an anteroom with access to the main club area. Depending on the night, this area isn’t as crowded and has its own bar. Two alcoves play host to a few VIP booths and the sliver of space between serves as the dance floor. Also on the first floor, the Red Room tends to keep things light and might provide an ideal space to strike up a conversation. But with easy access to the main room and entryway from the main corridor, you're just steps away from party.Vegas is now saturated with clubs with an outdoor patio but it was Pure Nightclub that revolutionized the concept when it opened in 2005 and it remains the best part of the place. It serves as a club within a club, or in this case outside of the club, complete with its own bar, VIP seating, dance floor and DJ booth. Most of Vegas' other patios give you the belief that you've left town, but Pure Nightclub puts you in the midst of the action with the lights of the Flamingo across the street illuminating the patio and views of the Las Vegas Strip.If the warm Las Vegas weather doesn't agree with you at least venture up to the entrance. You will traverse a white (what else?) staircase to a glass-enclosed hallway that wraps above one of the bars. You won't be able to stop here and truly enjoy the experience (security will tell you to keep moving) but you can at least take in a bird's-eye view of the club as you walk to the patio.Pure Nightclub also houses Pure Lounge, an alternative nightlife experience, every Monday through Thursday beginning at 5 p.m. Revitalizing the traditional lounge experience, live music is offered on a state-of-the-art stage. Performing multiple sets each evening and often accompanied by choreographed dancers, talented singers (like Suzie McNeil of the "Rockstar: INXS" TV series who opened the venue) are featured in limited-term residencies here.With so many different rooms to explore and experiences to have, it might take a few trips to take it all in!-- Review by Staff Member
