"The Fast Food Kitchen" is correct - as I said, a bit easy.
Hmmm, as for minimac's clue, well there's no level called Gibraltar, but to stretch the theme of an expanse of water separating East from West per se, I'll hazard a guess at "Stepping Stones".
EDIT: I just noticed that "The Fast Food Kitchen" was done near the beginning, with a very similar clue... sorry. I have a better one when my turn next comes.
