Bittersweet was the word of the night, the one often used to describe President Barack Obamas final State Dinner. We saved the best for last, he said Tuesday as he welcomed Italian Prime Minister Matteo Renzi and his wife, Agnese Landini, to the White House. He wasnt joking. The final gala meant everything was big or bigger, from the personality of the guest chef (Mario Batali) who collaborated on the menu to the size of the white tent (huge) on the South Lawn where the soirée was held, to the guest list (nearly 400 people).
