As reported by MCA, BigHospitality's sister brand, Beesley Corporate Recovery has been appointed liquidator at the three-strong brand.
The separate Gino D’Acampo chain of restaurants is not understood to be affected.
My Pasta Bar launched in 2013 and had a flagship restaurant on 40-43 Fleet Street, as well as sites in Leadenhall Market and Bishopsgate.
According to documents filed to Companies House, the business owes £4,939,332 to 49 creditors, plus £113,975 to HMRC and £37,887 in staff wages.
D’Acampo-branded venues in Birmingham, Manchester, Harrogate, Liverpool and Hull were bought out by Iceland supermarket boss Sir Malcolm Walker before the pandemic, and are part of the Individual Restaurant Group.
In May last year, the celebrity chef partnered with Spanish hotel brand INNSiDE by Meliá to launch a series of restaurants and bars across its growing UK estate.
This led to the launch of ‘upmarket’ Italian restaurant Luciano, named after D’Acampo's first born son, within The Strand-based ME London hotel.
Last week it was revealed by the Manchester Evening News that D'Acampo is to branch into Cheshire for the first time by swooping on the prime Piccolino site in Alderley Edge.
The restaurant will launch as Luciano Alderley later this month, with an opening date of 24 January listed on its Instagram page.
