[PICS] 1Oak Celebrates Grand Opening in Las Vegas
The NYC hotspot hits the other city that never sleeps

The Butler Group, consisting of partners Scott Sartiano and Richie Akiva, celebrated the grand opening of 1Oak, their brand new 16,000 square foot nightclub located in the Mirage Hotel over the weekend. The two night celebration not only welcomed the new hotspot to Sin City, but also benefited the GiveLove charity, who received a $50,000 generous donation. GiveLove was founded by Patricia Arquette and Rosetta Getty, with all proceeds going to improve housing and sanitation in poverty-stricken Haiti. Rumors floated around that Katy Perry, fresh off her divorce from Russell Brand, was going to perform. Alas, there was no performance from the blue-haired pop star. Other guests included Markus Molinari, David Arquette, Chris Evans, Christina Milian, Patricia Arquette, Chris Evans, Rosetta and Balthazar Getty, Christina Milian, Michelle Trachtenberg, and Shenae Grimes.

The party continued on Saturday night with DJ Jesse Marco, along with encore appearances by Michelle Trachtenberg and Chris Evans, and newbies Scott Disick, Lukas Haas, Bob Saget, Robert Iler, Miss Nevada 2011 Sarah Chapman, Shanna Moakler and an entourage of various pageant winners.
