Outrage in New York after Bill de Blasio uses knife and fork to eat pizza Mr de Blasio, who prides himself on his Italian-American heritage, later explained that he eats pizza the way they do in Italy. He starts with a knife and fork, then uses his hands. But owners of the restaurant, Goodfellas, said it was not acceptable practice in New York. "Hmm," co-owner, Scot Costentino told the New York Times, "I think he's just trying to be polite." We'll talk to him on the side about that. Even a friend of the mayor's, Charles Greinsky, said it was "blasphemy."
