The night I arrived, we dined with four delightful expat friends at a nice hotel restaurant, where I learned, among other things, that in 1992 a construction crew working for Ross Perot illegally blew up a coral reef so that he could moor his yacht, the Chateau Margaux, at his doorstep.
London's French-expat scene congregates in Frog Alley, otherwise known as South Kensington, which is home to the Ampersand, a hotel opened in August 2012.
