"Privée is our intimate venue for unforgettable wine experiences by La Reserve. Guests can choose from two distinctive and unique multi-course pairing dinners, each a sublime celebration of the finer things in life and limited to eight privileged diners per evening. Savor the truly one-of-a-kind Dom Pérignon Experience that pairs special Champagne vintages with thoughtfully crafted dishes or perhaps enjoy the exquisitely curated Odyssey Menu that is a gustatory journey for the senses. Dramatically backlit, debossed walls and a blooming flower petal ceiling, from which a dramatic chandelier descends over the polished marble slab dining table, only enhance the indulgent occasion. A wall of floor-to-ceiling glass provides an exhilarating view to complement these magnificent dining experiences that can literally traverse continents."
