I remember once meeting a couple in an airplane from Paris to New York, a very nice couple, who complained about the food in France, and how the Mcdonalds just wasn't the same, and would they please just open up a Burger King there.
I once made the mistake of speaking to an American gent in a restaurant in Rome. He knew that we were Americans from eavesdropping on our conversation, and commented to me how utterly astounding it was that I had spoken Italian to the waiter. The foolish part was that we actually conversed with him for a minute, and at one point asked "Did you have the prosciutto and melon?" and he answered, "no, haven't had that and we've been here a week. Ham and melon - I just can't see that combination."
But at the same time, we have to admit that there are still a whole bunch of people who have had a taste of what traveling can offer them in terms of adventure to the palate, and are hungry for more. I don't think that, for example if gastro-tourism were to really take off and we had the huge majority of Americans crawling the globe looking for authentic this and authentic that, it would homogenize things, no way.
Well, based on the numbers that people are quoting, and on all the various experiences like ours, do you think it's more likely that there will be a burst of Gastro-Tourism in numbers sufficient to keep foods from homogenizing, or do you think that in order to keep tourism alive, restaurants in tourist desinations will start to accommodate the McDonalds and Burger King Lovers even more?
