For some reason "brushetta" is the one the sends me most round the bend. Perhaps because, for whatever reason, it's not only a common mispronunciation, it's also one that seems to provoke mispronouncing miscreant waitpersons to then airliy correct you if you dare to pronounce it correctly yourself. Grrrr.
I'm not one to get all up in anyone's face about perfect pronunciation, but I think that restaurants can at least train people to get the basic sounds right. If your average waitperson can pronounce "linguine" correctly, then it shouldn't take too much extra effort to get "bruschetta" and a handful of wines right too.
It was at a special burgundy wine-tasting dinner that a waiter, years ago, came up to our table and gravely announced that the next wine would be a Volnay Les "calories." There we were, 4 or 5 people, desperately trying not to burst out laughing while the wine description spiel went on and on and we started dropping our napkins on the floor as an excuse to duck out of sight for 5 seconds. Not because we wished the waiter ill in any way, or because we are insufferable snobs (though we may well be), but just because it popped out so perfectly wrong, and with perfect twangy confidence.
As to the original post in the thread, I think what we're dealing with here is "faux-caccia."
