London is gasping — so where to go but Soho, which is so good at despair? It is often necrotic but now, of the central London districts, it feels the most alive. Mayfair is a pretty corpse — I pity the luxury services industry, for its clients are in hiding — but Soho’s restaurants have spread themselves on to the streets and it feels as interesting as it used to, a place that has found its purpose again.
