Dubens's firm Oakley hungry for Ed's Easy Diner

Hip, high-end burgers - think Honest Burger, Dirty Burger and, possibly even, Byron Burger - are all the rage with British trendy, metropolitan types but it seems like the City's private equity firms are more interested in tired, old burger chain brands.

Indeed, I hear Oakley Capital, the private equity firm set up by entrepreneur Peter Dubens, has been participating in the £100 million auction for Ed's Easy Diner, which I used to visit in my teens.
