Quaker Crunchy Corn Bran was a cereal that had a terrible name, but was SO yummy. Puffins are similar, but not quite right.
Ocean Spray made a Cranberry Key Lime cocktail for a very short while and I loved it.
Eggo used to make a Nutragrain version, and since I only eat toaster waffles with peanut butter and syrup, I couldn't taste the difference and it made for a healthier breakfast.
I have nostalgia for things like Clearly Canadian and Orbitz, but pretty sure I wouldn't actually like them anymore.
