Can anyone tell me how to steam oysters?

I love steamed oysters especially the Oyster Roasts that they have at Hooters. We are planning a trip to Myrtle Beach at the end of the month and I thought that it would be fun to go to the fresh seafood market and buy fresh oysters and have our own oyster roast. Can anyone give me the best way to cook them? How long? How will I know if they are done? Also, how can I make "drawn er"? Thanks for any help with this as it will be the highlight of my vacation if I can pull this off!
