A museum dedicated to a soft drink may not seem the most promising of ideas but World of Coca-Cola is actually a fascinating insight into the history of the brand (invented in 1886, just a few blocks away, by Atlanta pharmacist, Dr. John S. Pemberton). Attractions include a 3D film theater, art gallery, memorabilia (including classic Coke-branded delivery vehicles), tasting lounge and a fully functioning bottling line. As you'd expect of the world's No.1 consumer brand, the whole experience is exceptionally well done.
If you go:
