Albert and Michel Roux Jr have extended their agreement with the Langham hotel in London to operate the hotel's restaurant, Roux at The Landau.
The initial three-year partnership, which saw father and son working together for the first time in over 20 years, has now been extended for a further four years.
Roux protégé Chris King will continue as chef de cuisine, building on his experience gained at the Michelin-starred kitchens of Le Gavroche and Thomas Keller's Per Se in New York. Industry veteran Franco Becci, restaurant manager, continues to lead the front of house team.
Albert Roux said: "We are pleased to have contributed to a significant improvement not only in the restaurant's overall performance but along with our rising star Chef Chris, have also now firmly established Roux at The Landau as one of the capital's leading destination restaurants with many returning customers."
Duncan Palmer, regional vice president for Langham Hotels and managing director of the Langham, London added: "We have enjoyed a very fruitful collaboration with the formidable talents of Albert and Michel Roux Jr.
"Now we can continue to build on the restaurant's acknowledged standards of elegance for seamless service and exceptional food, nurturing our regular clientele and providing memorable experiences for diners."
