This bar is best experienced with other people--just in case you or they do not like it. As a couple of reviewers indicated, they thought the taste was off. When I heard about it, I thought it sounded disgusting. However, when I tried it, it was delicious, delightful, and stunningly good.
If you're expecting standard chocolate flavors, I don't think this is the bar for you. However, if you like odd combinations, enjoy fatty or greasy or salty food (like fries & chips), and enjoy new experiences, this bar is worth it. Sure, the price is a bit high, but the quality is top notch.
If you buy the bar, or if you like it, I suggest you bring it to a group gathering where you can share it. You may well convert other people who enjoy it, and those who don't enjoy it won't spend their money on it.
This is probably one of the best bar's I've ever had, and I love to share it with others!
