Update: There's a Coca-Cola museum in Atlanta. Here's the official site. And here's a review in the NY Times:
And after visiting the company’s new museum; after sitting in a theater, wearing 3-D glasses, feeling floating bubbles pop against my skin from well-timed puffs of air; after strolling through an exhibition hall with antique Coke ashtrays, vending machines and vintage ads; after watching a fully operational bottling facility produce the magic liquid; and after sampling nearly 70 different sodas made by the company, I can readily testify: Coke is It.
