Yesterday, former mayor Ed Koch celebrated his 85th birthday a little early (it's December 12), with a party at the St. Regis Hotel. Guests included Mayor Bloomberg, former Gov. Mario Cuomo, Police Commissioner Ray Kelly, former Senator Alfonse D'Amato and Dr. Henry Kissinger—check out this picture of Koch in a crown-like chair! He reflected on his time as mayor—"I thank the people of the city of New York for having given me their confidence and their trust and the opportunity to do what I loved so much"—and discussed his post-quadruple bypass diet (he needs to gain weight), "Ice cream, Peking duck, Peter Luger's steaks -- I'm doing it under doctor's orders! I'm doing terrific. I'm enjoying my life."
