Our daughter lives in a Sydney suburb called Rose Bay. When we visit we always enjoy bowls of coffee from a little café called 'C'est si Bon' run by a lovely French couple. Of course we must also have pain au chocolat for a little dipping. They always tell us 'Pas de calories'
Ok, even if French drink coffee from the bowl... still doesn't make sense.
A bowl and coffee ???. Can't see what it means in English.
A bowl of coffee probably would be the closest English phrase to describe this specific French custom.
