there is definitely southern and midwestern cuisine.

theres also "cookout" and/or barbecue type stuff, which can overlap with the aforementioned regions.

sometimes american vs elsewhere is more subtle - like hotdogs vs other sausages.

california has also gone "organic" etc crazy, which has spread to a certain degree, and im not saying its not found in other countries, especially naturally, but nowhere else has the same kind of (pop)culture.
