Flat Iron, the ‘single-steak’ dining concept, has secured a fourth site in London, in Shoreditch, M&C has learnt.

The concept, which was launched by Charlie Carroll at the end of 2012, is believed to have secured 77 Curtain Road for an opening next spring.

The group is set to move some of the space vacated by Porters restaurant in Covent Garden later this autumn, where its neighbour will be Frenchie, the bistro concept from chef Gregory Marchand.

It will be the third central London site for Flat Iron, which currently operates in Soho’s Beak Street and Denmark Street.

Porters announced in January that it was relocating to Berkhamsted to re-open in mid-2015 in a 3,000sq ft space.

It is understood that Flat Iron has been looking for further 2,000sq ft-6,000sq ft units in highly-populated areas such as Waterloo, London Bridge and Islington.

The concept was launched as a pop-up restaurant upstairs at the Owl and Pussycat pub in Shoreditch.

The business, which includes former M&B operations manager Mike Palmer, and current Benito’s Hat chairman Jay Travis, is based on offering a butcher’s cut called the flat iron.

Davis Coffer Lyons (DCL) and Dominion are believed to have acted on the Curtain Road deal.
