Milk chocolate has always been my preference, but I've been starting to like dark chocolate little by little. I just don't care for the bitterness most of the time though.
I LOVE dark chocolate, but I just love milk chocolate more... :x Milk chocolate just pairs better with more things imo. Milk chocolate with nuts especially. Although dark chocolate better suits caramel, since caramel is so sweet.
I'm not a huge fan of chocolate in general, but I'd never turn down dark chocolate if mixed with mint or pistachio of some kind. Godiva has these pistachio crunch truffles that will seriously own your soul.
