A favorite memory is the year I spent Christmas there....The staff even prepared a roast hen with chestnut stuffing for my solo Christmas Eve dinner served en suite....When Oscar de la Renta was designing Balmain couture, he, his wife, Annette, and I would wait for the room-service trolley of grillet fillet and sautéed spinach for dinner....
This is the Ritz's official site, though I understand the beautiful hotel is or will be undergoing renovation: http://www.ritzparis.com/ . There are beautiful pictures at http://www.interiology-ny.com/hotel-design-the-ritz-paris .
