On Friday, Diablo's and Brand hosted a two party celebration for The Grand Opening of Frank Caliendo's new comedy show. The red carpet and welcome reception took place at Diablo's where signature beverages were passed to the likes of celebrities, MGM executives and Frank's family and friends. The after-party was hosted at Brand Steakhouse and Lounge, and featured a premium open bar and tray passed specialty cocktails. The party lasted a little under two hours, but many guests chose to stay in the Lounge, where DJ Guy Williams was spinning a high energy mix of new hits and old favorites.

That same night Entourage star and Las Vegas regular, Jeremy Piven stopped into The Bank Nightclub while in town for the fight. The funny man partied and danced the night away while enjoying the company of flocks of doting females.

At a nearby table was Robert Kardashian, who was in town to relax and party with friends while staying at The Mirage.

On Wednesday, Sugar Shane Mosely, current welter weight boxing champion, dined at STACK with his manager and friends. The group dined on a heavyweight meal of rib eye, organic roast chicken and mac 'n cheese.
