For once, you don't need to stay up past midnight to see Jimmy Fallon when the Late Night host serves as the guest of honor on tonight's Top Chef All-Stars. To celebrate his 36th birthday, the reality-show fanatic invited his friends and family to a three-hour feast prepared by the eight remaining cheftestants at Manhattan's Colicchio & Sons. "I'm so lucky," says Fallon. "It was really like something where you go, 'Oh, this is crazy — I can't believe this is happening.'" Adds Fallon's mom, Gloria, "His birthday parties as a kid weren't this elaborate. We'd go to McDonald's and play games in the backyard."
