Head to Le Cirque at the Bellagio and just whisper the words "ultimate surf and turf” to land executive the restaurant’s take on this over-the-top dish. Guess what? It contains almost every ingredient in the kitchen — Japanese wagyu steak covered in perigourdine sauce made from truffles and topped with foie gras and finished with a layer of shaved truffles.
