KPMG says these include 27 Patisserie Valerie cafes , 19 Druckers stores, and 25 Patisserie Valerie concessions in Debenhams, Next and motorway service areas.
The group’s remaining 122 sites will continue to trade while a buyer is sought for the business.
Patisserie Holdings fell in to administration on Tuesday after it failed to reach an agreement with banks.
Amongst the closures is the iconic Patisserie Valerie on Old Compton Street in London’s Soho.
There has been a Patisserie Valerie in Soho since the 1920’s, when it was opened by Madame Valerie on Frith Street.
It moved to nearby Old Compton Street after the area was bombed during World War II, where it has remained open ever since.
The site is the second long-standing Soho restaurant to close in the last month. The original Ed’s Easy Diner restaurant, opened by the chain’s founder Barry Margolis in 1987, has shut its doors and is being converted to US import Slim Chickens by its owner Boparan Restaurant Group.
