This pub has a tremendous literary heritage being the favoured watering hole of people like George Orwell and Dylan Thomas and this is reflected in the number of framed photos and other documents that adorn the walls.
Named after the Fitzroy family who were ennobled by Charles II the pub is credited with giving the London district of Fitzrovia it's name. It is now a Sam Smith's pub, which in London is a bit of pub schizophrenia - as Smiths on the one side spend a lot of cash on preserving the pub's original features but on the other only sell their own keg beers, which are pretty uniformly putrid. The exception is the Imperial Stout which is not unlike Guinness. I do find it puzzling as Sam Smiths make a very fine cask conditioned bitter (Old Brewery Bitter) but don't stock it in any of their London boozers.
So worth a visit to soak up a bit of London's literary heritage, enjoy a pint of the black stuff but carry on down to the Marquess of Granby if you want a pint of proper beer or decent lager.
