Social lions gathered at the New York Public Library’s “Library Lions” black tie benefit, including indomitable society queen Brooke Astor (who just turned 99!) and David Rockefeller, playwright John Guare, Liz Smith, and Peter Jennings. Mrs. Astor’s humorous speech kept the audience begging for more, and the Rich & Glitzy savored a fab dinner of river trout mousse, roasted breast of capon with cornbread stuffing, string beans and sweet potato puree, and spice cake with chestnut ice cream for dessert. A feast for any lion.
