The World of Coke was awesome.  It helps Diet Coke is my favorite bottled beverage.  I enjoyed explaining to my Grandson and Nephew the early days of Coke, the price increases, having to return bottles, and the debauchery of "New Coke".  Well worth the time for a visit.  I would allow several hours to see all of the stations.  The tasting room is awesome.  All of the flavors are ice cold, just the way they should be.
