I love the flavor that this hot chocolate has. It is very rich and smooth. Have tried other brands but did not get the results I wanted. I will definately be ordering from this company again.

Once again, Paragon has disappointed with this flavor. The Hawaiian Tropic, simply did not carry much flavor, and what you could taste was not pleasant at all. I do not recommend this syrup concentrate.
