Byron, the fast-growing chain of up-market burger restaurants, has secured its 19th site in London, after taking a lease on the Black Horse in Rathbone Place. The chain, which is led by Tom Byng, is set to open a 90-cover restaurant over two floors in December on the site, which is next door to what will be the new Tampopo. Byng told M&C Report: “We’ve been looking in Fitzrovia for a while, it’s a beautiful historic Victorian building which we’ll respect in keeping with our reputation for individual design. We have lots of fans in the Charlotte Street area so it’s great to be bringing Byron to their doorstep.” The group recently opened its 17th site in the capital in Northcote Road, Clapham. An 18th at the Central St Giles Piazza development in the West End will open in November. Byron will also open at the Greenwich Promenade scheme before the end of the year. It is thought the chain will take its first steps outside London next year. Nick Weir of Shelley Sandzer, who acted on the Rathbone Place deal, said: “After the recent Tampopo deal Rathbone Place is becoming an interesting dining location in its own right. For years it was overlooked as a link to Charlotte Street but with the redevelopment of the Post Office Sorting Office and other developments taking place the area will only grow and Byron will benefit from this.”
