Ok, here's an example of a difference between East/West when it comes to some foods.

I love bagles and cream cheese. Yet, I would venture to guess that if you asked most Californians what Lox was they wouldn't know. Do they have lox here? I'm sure they do. I couldn't tell you where to by it (them) though.

To be honest, I know I've been told what lox is but can't remember. A fish??? Ok, laugh but hey I don't get out much.
