What quality improvement do you think McDonald's needs? They have already gone to excessive lengths to appeal to parents and advocacy groups by adding healthy meal options (apple slices, milk, salads) and reducing portion sizes (which helps them more in the profit department, than it helps the overweight consumers) and clearly showing the breakdown of each item on a large prominent poster near the register. They're a fast food restaurant who has already gone above and beyond all of their closest competitors IMO.
