I have tastes that don't go for the more expensive stuff I suppose. I've been all around the world, eaten at many places of great exhibit and taste, but the best places are almost always places you wouldn't imagine. (for me, at least. Eventually you realize, at least for many, that the places that cost a lot are many times selling an "experience" more than what the food is, and if you really want the food, go to the street and find out what is actually really popular among the people who live there. The more popular a place, no matter how cheap, is probably where you are going to find the food that is actually what they like more and tastes better...at least for me).
And interestingly enough, I've always come back to American Fast Food as what I would prefer as the best of the best in the US. At the top of it all (though, go back to when they used the real method of cooking them), the best fry there is are the ones from Mcdonalds (as long as you eat them fresh).
