There was a brief stop in Windsor, where Katie was finishing up a work trip.But we were largely in London, staying at the Mondrian on South Bank.We visited some excellent bars.And we drank many excellent cocktails, like this “Chico de Ganso”: Ron Zacapa rum, black cherry emulsion, chocolate, orange, lime, Orinoco bitters, yoghurt powder.We ate many things.We spent time with many friends.We even managed to catch up with my parents, a quarter of the way around the world.And we explored a great city that I have steadily grown to love.
