When I’ve seen it, the menu item was something like fish or lobster mostly, presumably because the cost to the restaurant can change as the prices as the market change and depending on the size of the fish or lobster. Otherwise, I’ve only seen it for rare/exotic meats like alligator or rattlesnake.
I’ve been to several countries in the EU and never seen a restaurant without explicit prices.
