Anheuser-Busch Brewery

One of the world's largest beer plants, the historic Anheuser-Busch Brewery gives marketing-driven tours. View the bottling plant and Clydesdale horses. One thing to note: the purchase of this St Louis (and American) icon by Belgium's InBev in 2008 is still a sore spot locally. And don't ask: 'How do you remove all the flavor?'
