I remember liking coffee ice cream as a kid, but I don't like it as an adult. Dunno why, it's the only case where my taste changed to DISLIKE something as I grew that I can think of.
I've always loved chocolate ice cream though. At ice cream shops I used to load up on extra chocolate (sprinkles, brownie bites, chips, syrup, hot fudge) but now I like it more simple, maybe with just some syrup on top. Aside from coffee though, the only flavor of ice cream I don't like is mint.
I also really like sherbet, though I don't eat it very often compared to other ice cream.
