Of the few Hot Cocoa flavors we've tried, this is the best so far.  It has the richest flavor and I dont notice the artificial taste that others have commented on.  Its also very affordable compared to other k-cups right now.  I thought that the k-cup making process must have gotten more expensive over the last year, but now I know they are truely sticking it to us since these are still reasonable priced.

Ex Input:
This tastes like carbonated orange juice, very tart.  It is very expensive compared to easier-to-find similar beverages.  If one had allergies or health issues, it might be worth drinking.
