Noble Inns, the London-based gastropub operator, believes there is potential to operate up to five sites under its Smokehouse concept in the capital.

Executive chef Neil Rankin said that Clapham, for one, is an area where he believes it will work.

He said: “The pubs have to have a certain look and feel to them, they need a good outside space for a start.”

The business, which also operates the Bad Egg fast-casual concept, is also considering a central London location.

He said: “It would be more like a smaller Goodman. It wouldn’t be a fast-food place, that’s the space Bad Egg fits into.”

The group opened its second Smokehouse site at the former The Hole in the Wall pub in Chiswick earlier this year, after launching the format in Islington in 2013.

Earlier this year, the company, which is led by managing director Simon Holroyd, set up a separate company for its new diner-style concept Bad Egg that it hopes to grow to “10-plus” sites over the coming years, with possible expansion overseas.
