There are, uh, plenty of crocs and pajama pants at the many New Orleans McDonald's locations.

I also don't think the US ended up absorbing much British cuisine, certainly native food(s) and immigrant waves have contributed much more than England.

Culinary traditions are far more recent than Europeans pretend they are. Anything with corn, potatoes or tomatoes is necessarily less than 500 years old.

Sounds like American culture is leaking back across the waves to France.
