Thé world "delicatessen" iself used in North countries probably following England speakers or maybe German one influenced by the France from that time, is incredibely meaningfull. In roman langages it would have logically been originated from the over-sophisticated french culture wich invaded and defined the rest of the world in that scope, but it's not the case. In french we even use an australian origine for the very french "croissants" ( thatis "vienoiserie", from "Vienna"). Lexically "delicatessen" is from a very very délicate and crafted high expectation product. A way to over sell a hand made product probably..at least a nice looking/sounding word and word.
