With a large crew of guys in tow, the Maroon 5 singer, 35 – who will soon tie the knot with model Behati Prinsloo, 25 – headed to Sin City following The Voice finale. And for this bash, no ordinary room would do.
The group of about 50 partied in the Palms Casino Resort's Hardwood Suite, a 10,000-sq.-ft. room equipped with an indoor hoops court, professional locker room, dance floor and 24-hour butler service.
The party didn't just stay in the suite – though it certainly could have – as PEOPLE's reigning Sexiest Man Alive and his party dined at the famous N9NE Steakhouse on Wednesday night.
"Everyone in the restaurant recognized him," a source close to the singer said. "He was saying hello and chatting with everybody in the restaurant."
The group sampled most of what N9NE has to offer – chilled seafood platters, steaks and salads. They were also seen drinking shots of high-end 1942 tequila.
Later, Levine was spotted gambling in the Mint, the Palms' high-limit area.
But the extended bachelor bash was far from over: On Thursday, Levine and his crew headed to the desert, where they rode dune buggies.
