The best soft drink on Earth - my vote is for Barq's root beer. The the 50's and 60's it was A&W for me, but it hasn't been the same since the 70's.
Barq's Root Beer gets my vote as the best!

Previously used in the pharmaceutical industry (much like Dr. Pepper), this delicious nectar now comes in nearly 300 flavors, and is microbrewed with nearly as much vigor as its alcholic cousin, pure beer. Root beer is so named due to it's ingredients, including berries, spices, and actual roots and stems from various plants.
