Chateau is one of Vegas's newest hot spot, located in the Paris hotel it offers a venue for both live and DJed events, Tonight they had Flo-Rida preform. They have a sizable dance floor along with an outdoor area over looking the strip.
We had a group of 25 people so they sat us outside where we would have more room to dance and socialize. They have excellent service here and really took care of us.
I would highly recommend getting bottle service to save you time and the headache of trying to get into Vegas clubs.
