The tour itself is mostly self-guided through a number of exhibits. Plenty of old Coke memorabilia, a short film, the 'secret' of Coke. The tour guides could do with a bit more knowledge though... There were a number of large Coke bottles on display at the main entrance, which were decorated to represent the country they came from. The bottle that was clearly from New Zealand (I'd know, that's where I'm from) was pointed out by our guide as being from Portugal!
Highlight is the soda fountains at the end which are great to sample the many variants amongst the Coke product lines.
