With so many journalists in town for the G20 summit, all needing to eat, I found myself wondering how foreign hacks view the London restaurant scene these days. The lobbyist friend from Washington I was meeting for early drinks was in no doubt about how much things have improved since the last time she was here, eight years ago. She's noticed that the city has developed a distinctly European flavour that was lacking before, and that it is much easier to find a decent cup of coffee.
