Paul Campbell, the chief executive and founder of Clapham House Group – the casual dining chain that was recently sold to Nando’s - has stepped down from the group to launch his own restaurant investment business. Campbell is to launch Hill Capital as an advisory and investment fund focused on corporate strategy and investment in UK restaurant businesses. He hopes to repeat the work of Clapham House in identifying scalable eating-out concepts. The fund will take over Campbell’s existing investments in Tortilla, the five-strong London-based Mexican Grill operation and Hawksmoor, the British steakhouse and cocktail bar business that has recently opened its second restaurant in Seven Dials, Covent Garden. Campbell is on the board of both companies. He said: “I had enormous fun establishing and building Clapham House over the past seven years. The company now has well-resourced new owners who understand the casual dining market as well as anyone. I am sure the Gourmet Burger Kitchen and The Real Greek brands will continue to thrive. It is time for me to move on to new challenges. “I will make investments in five or six businesses which have the genuine potential to carve out a niche and make a mark in today’s rapidly changing dining out market.”
