So, you're in Atlanta with some time to kill. How can you not visit the World of Coca-Cola? And it really is a Coca-Cola world. Here, you will find the whole story of Coke: it's beginnings in the pharmacy of John Pemberton (who served it at room temperature), it's evolution through clever marketing, the imitators, examples of the bottling machinery, it's presence in pop culture, and more. Highlights of the self-guided tour include a free sample mini can, a photo opportunity with the polar bear, the vault where the secret formula is held (don't cross the line), and the Taste It room, where you can sample the company's beverage flavors from around world (pace yourself; there are a LOT of options). Like any good tour, it ends in the gift shop, where you'll find all manner Coke-branded merchandise. Conveniently located within walking distance of several downtown hotels, this is a great way to spend some time. Tickets are a bit pricier than I would have guessed but you'll kick yourself if you don't go.
