The venue, which will serve high quality 30-day aged steaks in a variety of cuts and sizes, will be located on Princes Street, with the restaurant occupying a former New Look building.
The destination all-day steak restaurant is part of an extension to the Princes Street Premier Inn hotel next door, which Whitbread also oversees operations at.
On opening, the restaurant will be the second Bar + Block Steakhouse in Scotland and follows the opening of the first restaurant on St Enoch Square in Glasgow in June and the 18th site to open across the UK, all of which are located adjacent to Premier Inn hotels.
John Underwood, construction project and programme Manager for Whitbread, said: “It is a privilege to be leading the development of one of the first restaurants to open on Princes Street. It is a complex project as we are building a 60-bedroom extension and delivering a new restaurant in a busy shopping area at the same time.
“The location is superb and Bar + Block’s all-day flexible trading format, from breakfast through to dinner, lends itself to the location. I am confident that we will have a busy restaurant on our hands.”
