There's something thrilling about sipping fine champagne from an elevated perch high above the din and bustle of one of the world's most vibrant cities. Dubbed the world's highest outdoor Champagne bar, Flûte A Perrier-Jouët Bar is an altar to Champagne-and-caviar pairings, offering no less than the finest bubbly (from Bollinger, Special Cuvée to Perrier-Jouët, Belle Epoque) along with luxurious Royal Oscietra grains.
