For years green activists, who seemed to think that this American hamburger chain was solely responsible for childhood obesity, the hole in the ozone layer and the Kennedy assassination, looked down on McDonald's. Their harsh criticism was not ignored by the multinational's management and since then the fast food leviathan has made some big steps forward. This particular branch in Amsterdam Southeast for example is the greenest Golden Arches in the world. Solar panels, solar collectors and a number of other inventive devices supposedly illustrate the company's concern for the environment. This obviously doesn't effect the flavour of a Big Mac or a McFlurry, so what about the obesity? Two fitness devices in the Gym & Fun corner enable you to burn off the calories you've just taken in.
