London’s gigantic, seven-storey toy store is loud and frantic, with swarms of over-excited kids and model planes circling overhead. Hamley’s enormous selection ranges from tin soldiers and a sweet factory to the latest in Jedi fighting equipment and remote-control choppers. There are dressing-up departments, a Lego World, mountains of stuffed toys, in-store magicians and a cafe for birthday parties. Everything, in fact, except peace.
