Twist by Pierre Gagnaire

If romantic Twist's sparkling nighttime Strip views don't make you gasp, the modern French cuisine by this three-star Michelin chef just might. Seasonal tasting menus may include squid-ink gnocchetti topped with carrot gelée or langoustine with grapefruit fondue, finished off with bubblegum ice cream with marshmallow and green-tea crumbles. Reservations essential; dress code is business casual.
