Example Input: Ghirardelli isn't the finest chocolate you can buy, but it's pretty good, and the Intense Dark Assortment is both inexpensive, and provides you a few possibilities.  I've lately taken to unwrapping a 60%, 72% and 86% cacao square for each dinner guest and setting them on an individual saucer, to serve as an after-dinner sampler with red wine or Scotch. That's been a pretty popular approach. A similar approach also works "therapeutically"---if someone's having a bad day, sitting them down with a small assortment of increasingly intense chocolate isn't a bad path to feeling a little better.  I do wish that there were the same number of each in the bag; that's the only downside. Of course, if you really want the sets of three to serve to guests, you'll have to go through the tiresome task of somehow eating the extras. Darn.

Example Input: This was not your usual granola bar looking snack.  It was somewhat misshapen making it look more home made.  It was soft which was a plus.  I liked the coconut.  My son, two of my grandchildren and my wife did not like the coconut.  On first glance it seemed yummy, what is not to like about oat, chocolate and coconut?  Obviously in my family the coconut was a negative.  Son liked the taste but not the coconut. Wife didn't like the taste and neither did the 5 & 7 year old grandchildren.  If you are looking for a gluten free non-dairy snack and have no issues with coconut or calories this is a good choice.  The 180 calories put it about 40 calories higher than our favorite granola bar and 80 calories higher than my favorite snack bar.  Uber-sensitive son was dismayed with the lack of protein and he was concerned about the 9grams of fat.  Wrapping it up, for a gluten free snack it is pretty good but if you are not concerned about gluten you probably will want a different snack.  Addendum:the counter woman at my favorite pizza place is on a gluten free diet and loved them.  So that confirms it, as a gluten free snack it got the prize!
