No wonder the domestic dinner party seems a little jaded by contrast. Rowdy arguments, whispered confessions, drunken flirting, awkward silences - in restaurants they assume an intensity that would be alien in our own homes. Meanwhile, the preparation of food at home has now, like football, become a spectator sport, something we watch on TV. Men, once only conversant in Audi and BMW, now speak fluent Poggenpohl and Bulthaup. They love the idea of home cooking - and all the lethal, expensive, shiny arsenal of catering hardware that goes with the process, but when they want proper food, they eat out.
