It's not part of the factory or HQ. It is actually a museum for the World of Coca-Cola. It is located in the tourist section called "Underground Atlanta". It's very educational plus as wonkapete can attest you get all the free soda you want. However, be careful. The taste of people from China, South America, Great Britain, etc is much different than ours here in the states. Some tasted plain awful to me but were number one sellers in their respective countries.
If you ever have a chance to visit i would recommend it.
Whether you think can or think you can\'t, you\'re probably right!
