Just go to the Annhauser Busch "hospitality" building, and you can get a free sample of one of several of their beers. They also do a fizzy lemonade for non drinkers. Its meant to be one per person, but they arent too strict. The Sea World hospitality area is in a nice spot, and you can sit outside near the pretty lake. There is also a small cafe that serve salads, sandwiches and baguettes. Always worth dropping in for a visit!
