Agree with other posters that this is worth a visit but it isn't awesome. Certainly worth seeing at least once.
The opening video is strange and a little creepy. The safe with the secret formula is also underwhelming. The other exhibits were interesting. You can see everything within 90 minutes or less. The tasting room at the end is far better than the one at Disney World since it has more choices and several freestyle machines, plus you get a free coke on the way out that is bottled on site.
