Discovery Travel and Living had an amazing show once where they
showed how this famous beach-side restaurant in Spain cooked their
Paella!
They had a huge flat-bottomed pan over a huge fire where they threw
in the spices and condiments, cooked the rice, and threw a ton of
assorted fresh seafood into it! 
Once it's been cooked, with the rice absorbing the delicious, tasty
stock, they'd heap spoonfuls onto large plates and serve the
customers straightaway! :-P~~~
They cooked their Paella in full view of the customers, in an
open-air corner of the restaurant. Man, what an experience it must
be to eat Paella there!
