The concept, which launched in Birmingham last year, is designed as a ‘contemporary’ version of Beefeater aimed at a younger demographic.
The 132-cover Bath restaurant will feature an open kitchen and serve ‘affordable’ steaks priced from £12.95 - £39.95, alongside burgers, salads and desserts.
It is also set to offer breakfast and brunch options alongside a ‘Express’ menu, with all dishes served within 10 minutes for under £10, when it opens on 28 September.
The launch follows the opening of a flagship Bar + Block in London’s King’s Cross in 2016 and a site in Whiteley this year.
“We’re very excited to launch our fourth Bar + Block Steakhouse in Bath as part of our wider brand growth strategy,” says Nathalie Pomroy, chief marketing officer for Whitbread Restaurants.
“Following the success in Birmingham, London and Whiteley, we are eager to see how our unique offering will be received in the beautiful city of Bath filled with real foodies.”
