They're the original cherry Coke and vanilla Coke, from before those flavors were sold pre-mixed (heck, pre-mixed vanilla Coke has only been the market maybe 10 years at the most--I remember ordering the real kind at diners when I was a kid, and I'm only 31). They're Coca-Cola with cherry or vanilla syrup in them, so the flavoring is much stronger. I think the cherry Coke has maraschino cherries in it also, there's a picture in my dining review.
