My wife and I are off to Venice, Florence, and Rome at the end of September on a 25th Anniversary celebratory adventure. I have a great list of restaurants for the trip -- thanks to the wonderful and knowledgeable folks on this board -- but wanted to find a particularly special place for dinner in Rome on the last night of the trip. By "special," I mean top-knotch food, service, and ambience. I'd appreciate any and all recommendations. With thanks, John.
