Sin City has been on a roll lately. The gritty home of showgirls and one-armed bandits has developed an air of refinement, and in 2006, Inc. named Las Vegas the hottest large city for entrepreneurs, reflecting the city's job growth of more than 25 percent over the past five years.

But if you're going to do business in Vegas, you need to know where to play, too. So we asked the owners of four area companies for their advice on where a high roller can let loose. Thomas Tait of Nevada Rose, Valerie Bent of Big Feet Pajama, Tony Hsieh of Zappos.com, and Matt Goldman, Phil Stanton, and Chris Wink of Blue Man Group guide us through Elvis's old stomping ground.
