50 Cent served free Thanksgiving dinners to Sandy victims Wednesday at Cipriani Wall Street. “Fiddy went from table to table, posing for pictures with a number of children,” said a spy, adding, “One kid was saying, ‘Can I have that plate he touched?’ ” Food at the Our Table Is Yours Thanksgiving Dinner — hosted by the Food Network, Cooking Channel and Southern Wine & Spirits of America — was whipped up by chefs including the Lambs Club’s Geoffrey Zakarian and Scarpetta’s Scott Conant.
