The Casual Dining Group – owner of Cafe Rouge, Bella Italia and Las Iguanas – has entered administration.
91 of the group’s 250 sites will close immediately, and 1,900 of its 6,000-strong workforce will be made redundant.
Administrators Alix Partners are now seeking offers for all or parts of the remaining business.
“We are acutely aware of our duty to all employees and recognise that this is an incredibly difficult time for them,” said chief executive James Spragg in a statement.
“Working alongside the administrators we will do everything we can to support them through this process with a view to preserving as much employment as we are able to.”
Reports suggest the company – the UK’s second largest midmarket dining collective behind TRG – has already received multiple offers for the business.
The administration leaves it trading with 159 restaurants.
