The other closures are on Clapham’s Northcote Road, Soho’s Kingly Street and Liverpool Street in the City.
Just two bricks-and-mortar sites remain: one in Canary Wharf and one in Brighton.
The group, which was founded by Joe Grossman in 2011, continues to operate a number of concessions at venues including Swingers and Lane 7.
In a statement posted to Instagram announcing the closures, the group said: “We’ve loved being part of these communities and just wanted to say a huge thank you to everyone who’s walked through these doors. It’s been a privilege to serve you.
“To our teams past and present, the graft, the energy, the madness and the love you put into every shift… we’re endlessly grateful.
“This isn’t goodbye to Patty & Bun. It’s just the end of this chapter.”
Twelve months ago, Grossman completed a restructure that saw the group’s assets acquired by a new company led by the existing management team.
This followed a CVA two years earlier that resulted in the closure of two sites.
It hasn’t been a good week for better burger brands. Yesterday, it was revealed that MEATliquor had shuttered the majority of its estate.
MEATliquor sites in Islington, Clapham Junction and Queensway have closed, along with its only regional outpost in Brighton. Additionally, The Dartmouth Arms pub in Forest Hill, which operated as part of the group’s estate, has shut.
The group has been reduced to three sites: two operating under its core MEATliquor brand in London’s Oxford Circus and East Dulwich, and its sister sports bar BLOODsports in Covent Garden.
