Ex Input:
Yes, tasty -- but it takes a little getting used-to.  You have to like coconut to like this snack item.  That taste quite overwhelmed all else, for me.  I found few chocolate chips -- maybe they were all taking a rest when my snacks were baked.  Anyway, it's a chewy but tasty item worthy of your consideration.  Give it a try.

The hot chocolate is my husband's favorite.  Service was also great, as it usually is.  Very popular now with winter coming on.
