Pastry, I would guess Austria since they have Wieners --what we call "Danishes". which is confusing since for us in the US "wieners" are "Austrian" sausages... but in Vienna, they are again called Danish pastries (Danisher plunder?).
Then you have the greek salad, well I'm from Bulgaria.. We ain't callin' it that way :) But since I've been living in USA for a long time, I got used to calling it that way...
