Alain Ducasse, the only chef in the world with three signature restaurants each honored with three Michelin stars, added another line to his résumé with Adour at the St. Regis, Washington, D.C., a sister restaurant to the original Adour in New York. The restaurant opening in September coincided with the completion of a 16-month restoration of the iconic St. Regis hotel, originally opened in 1926. Two glass-and-steel temperature-controlled walk-in wine cases are the focal point of the French-American restaurant; the cases separate the foyer from the 80-seat main dining room, and the dining room from the 8-seat private dining room. Among the rare vintages housed in the floor-to-ceiling partition include a red Domaine Comte Georges de Vogüé Musigny 2001, $850, and a white Meursault Premier Cru Perrières 2006, $450. A Krug Clos d’Ambonnay Blanc de Noirs tops the champagne list at $7,000. (www.adour-stregis.com).
