I have a thing for food where its like...
Fresh food normally when its being eaten around the first 2-3 hours that it was made, that food is normally heated, warm, and hot. This is probably the only few times I would prefer hot food, like pizza or chicken, because well, its Fresh!
However, food, especially ones that you had gotten through ordering from a fast-food, restaurant, etc, after a day or so...
Well, you normally put that sucker away and it tends to get cold. When you try to heat up the food again, at least for me, it doesn't have the same taste as it was fresh, and honestly, just doesn't feel right and tastes weird and icky.
I normally will always eat chicken cold than heated, because it just tastes better.
Pizza however, is like a different beast.
Pizza, tastes good, in my opinion, either cold or hot.
I think eating Cold Pizza is like, an "acquired taste" I guess (Kind of like how people acquire tastes for coffee or alcohol or etc).
I've rarely eaten Pizza Cold, because even though it doesn't taste that great heated (if its past a day old), it just feels more natural since that's how pizza is normally eaten.
But, whenever I want to transfer pizza to a Toast-R-Oven to be heated, I normally chew on the crust as I walk there, and--- Oh gosh, it tastes boooooooootifull.
Other times, cold pizza when the power goes out/we can't reheat it then and there.
BUT COLD PIZZA CRUST IS THE BESSST.
YOU HAVE TO TRY IT.
