I was just looking over the threads in TA where first time visitors are worried about not being able to find food that they'll be able to eat while in Paris/France. The idea that we eat raw mince / snails / frogs legs /duck liver *all the time* seems to linger still but I can see how some of those foodstuffs can turn people off.
Now IMHO most countries have something that most tourists are just not going to eat.
But I can't think of anything from the USA that I've never said 'Ugh' to that I was served in a restaurant or saw on a menu. Granted there are some processed products that worry me (cheese that you spray out of a can for example) but none that I wouldn't try at least once.
Have I missed something here? Any Us folks that can tell me what I should try next time I'm in the USA that I probably won't want to try a second time? :)
