I love pumpkin pie. Sadly, oh so sadly, I am allergic to it. I have a very nasty reaction each time I eat it. And yet, I am tempted to take a bite every time I see it. Life is that way sometimes.
Frankly, I think the curiosity about personal tastes is a legitimate topic for an "off topic" forum. People talk about what games, books, and movies they like. I don't see why discussing a taste in food is really any different than that.
In fact, we could have a very fascinating discussion about the differences in taste that exist between countries (just ask a Brazilian what they think of rootbeer, or an American what they think of Vegemite). Our tastes (including food preferences) are part of what make us who we are, and thus they would seem to be a valid area of exploration in this community.
My two cents.
