Mark Hix is set to open a new 5,000 sq ft restaurant and bar in the City of London.
The new site will sit in Devonshire Square and serve chicken and steak, according to restaurant consultant Adam Hyman's Code Bulletin.
There will also be a Mark's Bar in the basement.
The new opening will be Hix's ninth site. Seven of the existing eight are in London, while Hix Oyster and Fish House is in Lyme Regis in Dorset.
