Even by his own, crazy successful standards, Wolfgang Puck is having a red-hot winter: He's got a brand-new restaurant at the Hotel Bel-Air, he's set to receive a James Beard Lifetime Achievement Award, and he's of course getting ready to reprise his role as the caterer for the Oscars Governor's Ball this Sunday. "It's more like an ensemble of dishes, like tapas. So everyone can eat as much as, and whatever, they want," Puck says of the menu he's planning. And even he says he's watching his weight in advance of the big day: "I have a tailor-made fancy cooking jacket for the Oscars," he jokes. "If I gain three pounds, I won't get into it." But even with all that going on, Puck still managed to find time to hang out with Lenny Kravitz in Vegas, hit the Santa Monica farmers' market, and cater Muhammed Ali's 70th birthday party.
