The large-scale central London restaurants of the past decade may be wallowing in self-pity following 11 September, but local restaurants are booming. Tom Conran - who foresaw the rise of the gastropub when he opened The Cow in Westbourne Grove - has now opened a small restaurant, Lucky Seven , in the same neighbourhood. It is modelled on the American diner, a small eaterie producing excellent upmarket cafe food for a fashionable, yet local, clientele - just like Elaine's, in fact.
