There hasn't been any thread about the expression used when beginning to eat with others in different languages and I thought it could be worthwhile.
As far as I kinow in English there is no special expression for this purpose, they only say "let's begin" or "enjoy your meal".
The expression in the title of this thread is French (if written correctly) and I guess most of us recognise it.
The Germans have copied it to their mother tongue and say "guten Appetit".
In Finnish we say correspondingly, without using the original French word, hyvää ruokahalua (literally: "good desire for food".
In Spansh I would say "Buen provecho" that is literally "good profit".
How in other languages - and are my examples correct?
