What you are describing is a churrascaria, which was developed for Brazilian cowboys. They put a giant piece of steak on a stick, rotate it around a fire, and then cut off the cooked edge pieces. Plus the way the serve it is awesome, if there is something wrong with all you can eat filet, then I don't want to be right.
Best steak in the world, mostly because its not usually industrial raised like most places here in the states. If you don't believe that American cows are kinda crappy, just go to Lubbock and take a deep breath, then promptly throw up.
