Bellamy’s and Oswald’s are the two best restaurants in London. They are owned by two friends of mine — both gents, both English — and the service and food are as good as it gets. And it don’t get better, as they say in Chicago. Last Friday I got off the plane and went straight to Bellamy’s, where the owner Gavin Rankin, Tim Hanbury, annually voted father- and husband-of-the-year since 1980, and Charles Glass, left-wing author and right-wing bon vivant, were waiting.
