The company's chief executive cited increasing costs and over-supply of restaurants for the move.
Boparan Restaurant Group (BRG), the operator of brands such as Giraffe and Ed’s Easy Diner, announced plans to close a third of its sites.
BBC reported that BRG is planning to enter a company voluntary arrangement (CVA) to close 27 of the 87 restaurants associated with Giraffe and Ed’s Easy Diners as many of its sites remain unprofitable.
Tom Crowley, chief executive of BRG, told the media: 'We have been examining options for the two brands for some time and the CVA is the only option to protect the company.
'The combination of increasing costs and over-supply of restaurants in the sector and a softening of consumer demand have all contributed to the challenges both these brands face.'
Advisers from global auditing firm KPMG will oversee the process.
