We've all probably felt so hungry that we ended up daydreaming about the food in anticipation. Well, that's basically what this trope is: a character fantasizes about their food, either verbally (often with the line "I can just imagine the X" or "I can almost smell/taste the X") or via a Fantasy Sequence or Thought Bubble.
Differs from similar trope Meat-O-Vision in that Meat-O-Vision is about imagining the people around the imaginer turning into food, (although in some cases, they might briefly forget that it's all in their head). Delicious Daydreams are about food in general; the most surreal of these daydreams tend to be about Giant Food. They might involve a Mountain of Food.
When Played for Laughs, it means that the character is just being dramatic about how hungry they are and/or how much they like the food or food in general. When Played for Drama, however, it can mean that the character is literally starving or hasn't had anything interesting to eat in ages. Might also be done by someone (again, usually a Big Eater or someone who really loves the food) if they're about to go to a new place that serves delicious food or are imagining buying food with a large sum of money they think they will acquire. Compare Marshmallow Dream. Also compare, but do not confuse with, Delicious Distraction.
- In the original Fullmetal Alchemist, the first episode has Ed so thirsty from walking through the desert that he says "Water... I can almost hear it." Subverted in that he can hear it, as there's a fountain nearby. Double-subverted in that the fountain is a fountain of wine instead of water.
- In an Asterix book, Asterix and Obelix are in danger and Obelix, who is hungry, imagines some roast meat.
- In the Bear in the Big Blue House episode "Call it a Day", Bear is talking about the events of a typical day and when he gets to lunch, he imagines a stack of peanut butter sandwiches and says, "Mmm, peanut butter."

- The song "Food, Glorious Food" in Oliver!. The boys in the workhouse sing it to complain about the gruel they're being fed while fantasizing about the food they'd like to be eating instead. It praises delectable dishes like hot sausage and mustard, cold jelly and custard, pease pudding and a great big steak.
- JonTron: In "Food Games", Jon starts discussing how the McDonald's games are absolutely not going to make him crave "a delicious McDonald's hamburger, which has the perfect blend of crispy lettuce, meaty tomatoes, a patty sizzled to perfection, and all topped off with one, perfectly crunchy pickle." Immediately following is the sound of Jon opening a wrapper and eating one of the many burgers he ended up buying.
