Caring said the new restaurant would be "moved into the 2020s".
Le Caprice, the London restaurant once favoured by celebrities, is to reopen at the upcoming Chancery Rosewood hotel.
Restaurateur Richard Caring, who owns the Le Caprice trademark, told the Evening Standard the new site would “keep the essence” of the original while being updated for a modern audience.
It is expected to launch alongside the £1b hotel, which occupies the former US Embassy building in Grosvenor Square, in 2025.
The new Le Caprice will be split over two levels with a 120-cover main restaurant built around a large bar, a "year-round" terrace with 88 seats, and a 24-cover private dining room.
It will open seven days a week from 7.30am for breakfast until late in the evening.
“Le Caprice opened in 1981 and that’s 43 years ago,” Caring, who also owns the Ivy and Annabel’s, told the paper.
“I’m sure a lot of people will want to see Le Caprice as it was, but I believe it should be moved into the 2020s.”
The original Le Caprice in Mayfair was run by Jeremy King and Chris Corbin, who took on the site in 1981 and created a restaurant that attracted celebrity clientele including Princess Diana and Mick Jagger.
The restaurant was bought by Caring, who closed the site in 2020 during the pandemic.
King opened his own restaurant, Arlington, on the original site of Le Caprice in March.
The 139-room Chancery Rosewood will be led by managing director Michael Bonsor, who spent more than a decade leading sister hotel Rosewood London.
