If you haven't been to Marquee, then you probably live under a rock. This is what has been the "It Spot" since Town Center opened. Although it's not my favorite club, this place has never disappointed me.
About 3 years ago, I spent my 21st birthday here and had the time of my life. My latest visit was few days ago on a Friday. We got a comped table right by the dance floor which was pretty awesome. We were treated amazing by all the workers. I've never been to Marquee on a Friday and I don't think I ever want to again. That place is a total zoo! So many people. Me and my friends decided to go to the bathroom which was literally 10 feet away and got mosh pitted on our way there. Other than that we all had a great time. The drinks came flowing and the crowd didn't even matter.
Must go if you're visiting Vegas!
