UNCASVILLE, Conn. -- It's nearing 1 a.m., exactly one week ago today, and we've spent a couple of hours in clubland at the Mohegan Sun complex. We've modestly imbibed a martini or two, and maybe we're not seeing straight. In the semi-sequestered "white room," a private VIP booth at the nightclub Ultra 88, we seem to be seeing Johnny "Sack" Sacramoni, New York mob boss, and Christopher Moltisanti, Tony Soprano's "nephew" and a made man in Uncle Tony's New Jersey mob. Have we fallen through the rabbit hole? Is a deal going down? Is this club Mafia-owned? Are we on HBO? No, it's real life, and the actors who play Johnny Sack (Vincent Curatola) and Christopher (Michael Imperioli) on "The Sopranos" are in the semicircular booth, with six rather impressive-looking bodyguards nearby. A bottle of chilled Kettle One vodka arrives. Imperioli says, "I'm here every chance I get. I'm here to gamble and I did terrible. I lost money." Still, he's pumped for the night life.
