A sister thread to the beer one.
There are a few I can think of.
Doritos Late Night Cheeseburger - Dam things really tasted like a cheeseburger, right down to the hint of ketchup.
Sour Patch Kids Chillers - I'm huge sour patch fan, I know they aren't for everyone. These had some sort of menthol in them so you had this cooling effect in your mouth.
Blue Rasberry Blow Pops - I was totally addicted to these inhigh school. I thought they had the best flavor.
Crystal Pepsi - I liked it alot. Different than Pepsi Clear, which tasted like regular Pepsi. Crystal had a unique flavor.
