Oh, I agree with you. We have a very diverse and tasty cuisine in the US. Filled with foodstuffs that will blow even the most jaded gourmand away.

But if you're a tourist here for the first time in your life, this might well be the only time you get to eat a “real” Big Mac, Whopper, or burrito and potatoes ole. These are things you've read about and seen in movies and probably TV. So there ain't no shame in getting some chicken nuggets and dipping them in ranch dressing and really enjoying the food. And the most important part, where you ate that crappy chicken. It will be a lifetime memory.
