The ravages of Sandy haven’t affected the palates of New York’s power dining crowd. Newly opened Sirio Ristorante in the Pierre Hotel was going strong Tuesday with a crowd that included Nine West co-founder Jerome Fisher, Jerry and Judy Della Femina, Yaz and Valentin Hernandez, Florence and Richard Fabricant and Daniel Boulud. Lunch was busy with billionaire Ronald Perelman, Ivanka Trump, Aryeh Bourkoff, YSL’s Pierre Berges and designer Dennis Basso.
