Electric Diner is from the Soho House group, which has done terrible things to private clubs, luckless farmhouses, domestic interior design and even its own restaurants. The Ned, its City hotel with ten restaurants, is genuinely insane, like Thorpe Park for people who are scared of roller-coasters; and no restaurant for adults should sell fishfinger sandwiches, even at Babington House, a Soho House hotel which is Clown Town for grown-ups but near trees.
