I really like dark chocolate. I've always loved the flavor, and the health benefits are a nice added bonus. I like milk chocolate as well. I'm not a big fan of most flavored chocolates, however (e.g., nutty chocolates, fruity chocolates, etc.); I prefer my chocolate plain and pure. I did try a lot of flavored chocolate at a chocolate factory I went to a few months ago, though, and most of it was pretty good, though in the end, I purchased the more standard options rather than the unusual flavors.
I enjoy consuming chocolate in any number of ways (cakes, cookies, ice cream, etc.), but my favorite ways probably involves pure chocolate pieces or bars.
