What is this Chicory coffee and why does it taste so damn good?

Got three bags of Chicory coffee from a Mardi Gras style cake fed-exed in by a clinical motivational speaker from New Orleans this week, and I have to say it tastes damn good. I read a blurb on About.com relating to this coffee and panicked for a minute when I found out that Chicory coffee is naturally decaffeinated. I could have gone the whole week in a stupor and blamed it on my incessant late night boozing, had I not found this out! Later upon examination of the package, I found this to be "Coffee & Chicory" which actually is caffeinated. Foiled again -too much boozing.
