I miss chochlate that tasted good. None of the "major brands" have tasted the same since around 2003 or so.
As for discontinued products I used to like,
Royal Crown Draft premimium cola
Berry Blue cool aid
Ecto cooler from hi-c
Ocean spray Mauna La'i island guava
Keebler Potato Skins
Not a "food, snack, or drink" but sideways related... The old foam McD's containers.
Not all who wander, are lost.
I have become death, destroyer of worlds.
