Mark Sargeant has been named chef director of the Strand Dining Rooms in London's Trafalgar Square.
The all-day restaurant, owned by restaurateur Mark Harris, opened last year to poor reviews. Sargeant has been brought in to revamp the food offer, launching a new menu on 3 April, according to Bloomberg.
Sargeant, who worked for Gordon Ramsay for 13 years and won a Michelin star at Claridge's, will focus his new menu on classic British dishes such as lamb's kidneys and roast beef.
In addition to his new role, Sargeant runs Rocksalt restaurant in Folkestone, Kent, and also oversees the food at Plum & Spilt Milk at King's Cross station in London.
