Exactly what F P stated. I personally recommend to just pay for the premium because you have access to the whole menu and you can order anything you want from it as much as you would like, compared to choice, where they limit you on the menu.
They have 2 choices for AYCE: Premium and Choice. Premium is $47 per person and Choice is $37 per person. They also charge a different price for children, depending on height (I think). The prices don't include drinks. Drinks are priced based upon what type you get (non-alcohlic, alcoholic, etc).
Go for the $37. You won't have a big regret.
