It should be noted that McDonald's France rakes in over 5 billion euro per year.
Someone's eating it, and I don't think American tourists would account for it by an order of magnitude.
I also agree with the other poster that Italian food is far superior to French. So is Mexican (either "genuine" Mexican or Tex-Mex).
I've long had the impression that French food only got the reputation of being "good" because it was being compared to British food. :-)
