For over 3 centuries, the reputation of this member of the Comité Colbert (an association of luxury houses and historic cultural institutions) has meant that it is always in demand for major public and private events. Its teams of chefs, pastry chefs, maître d'hôtel and reception organizers perpetuate the French art of living and the quest for culinary excellence, including the hiring of 2014 French Dessert Champion Jérémy Del Val.
His creations, like the Opéra cake, Dalloyau's signature product created in 1955, can now be enjoyed in various boutiques and tearooms or, for a complete meal, in a secret setting at the Saint-Lazare train station. Since 2021, this former footbridge which, under Napoleon III, enabled Empress Eugénie to discreetly make her way to the Hilton Hotel from the train, has been a restaurant serving dishes by Top Chef candidate Justine Piluso.
