The Sauce “Café de Paris” was developed in 1930 by Chef Boubier who gifted its secret recipe to his daughter and her husband Mr. Arthur Dumont, owners of a restaurant called “Café de Paris” in Rue Mont Blanc Geneva; thus enabled them to launch an astonishing concept offering a single menu formula, consisting of a Green Salad, 180 grams of Entrecote Steak with “Café de Paris” sauce and French Fries. This simple formula gained immediate worldwide fame and success. The ingredients of this amazing butter sauce are still a secret till today.
