An autism friendly McDonald's?

I've just returned from McDonald's after treating my ASD son (young adult) to lunch. He isn't particularly noise sensitive but today found the whole experience overwhelming: loud music, bright lights, close proximity to chattering strangers....you get the picture. We are of course aware that it is a fast food restaurant and likely to be busy but my son enjoys going and I dont believe that he should feel excluded. Upon returning home with indigestion after a hurried lunch I began to wonder how other people connected with autism experience McDonald's. Is it somewhere you visit or avoid. I am now seriously considering if a multi million pound cooperation like McDonalds could follow in the footsteps of other organizations/businesses and address the issues of becoming more autism friendly, particularly for families. What do you think?
