Author Robert Kalich — famed for hosting weekly boozy brunches with guests including Robert De Niro, Barbra Streisand, George Balanchine, Michael Jordan, Al Pacino and Ed Koch on the 3,000-square-foot terrace of his Central Park apartment — is using the tales of his own eccentric past in 1970s and ’80s New York for his third novel, “David Lazar.”

Kalich — who once told Madonna that if she wanted to snag a good man she should “dress better” — has written a tome about a man who makes it big in the city after becoming a college basketball handicapper. He’s fictionalized many of his own true-life stories in the book, out Thursday, pals say.
