It does depend. If it is a particular meal, such as the one I made, or the one they are having tomorrow at a friend's house, or the one they make at the restaurant, those could be the breakfast, the lunch, the dinner/supper. You want to try the lunch at the new café? You did not eat the breakfast I made you. They did not serve me the dinner I ordered. The supper at Joe's was outstanding. And so on.
