I have seen many suggestions for this sort of thing my friend. I don't believe an entire event should be dedicated to just this. I think it would be a great idea though for a future RP event where Droobledore perhaps is giving a speech only for some sort of chaos to erupt, it could be a set time beforehand, half an hour before the event truly starts where the main gathering area is the greathall as people await for the events to unfold. We would need some sort of food mechanics that would make it interesting though, and eating food, I'm really not sure how you could make it interesting. I think this is a sort of idea that could be implemented into something better but is defintely, in my opinion not worth our developers resources to work on making eating food interesting nor most of the players time.
Edit: Plus with revelius we will have no food hotbar anymore.
