See, I think some of you are doing it wrong. Guilty pleasures should be something that is either odd/unusual or totally out of character. My example was chicken gizzards. A lot of people think that is gross or odd, but I love them. My musical guilty pleasure was BeeGees because a lot of people think they suck and hate disco. A guilty pleasure is something you are more or less embarrassed to a degree to admit to.
Not trying to knock participation, but saying icecream and Mexican food are guilty pleasures is pretty vanilla. Now if you said, I like booger flavored icecream or bull testicle tacos, than urdoinitrite.
