In an attempt to woo customers back to its restaurants after a disastrous year, McDonald's is opening up its kitchens to the French public as part of a massive charm offensive. The fast food giant plans to open up over 400 restaurants across France for two weeks, starting this Sunday, and give consumers access to information on everything from McDonald's meat suppliers to the preparation of a burger and the way the company's PR agency has handled the crisis in public confidence over meat. McDonald's suppliers have also been persuaded to open their doors to the public.
