The only dining plans available are the Disney Dining Plan add on, the Premium Package add on, and the Platinum Package add on. These options MUST be added on to a Magic Your Way package (including hotel/park tickets). DDP allows one snack, one counter service meal, and one table service meal at over 100 restaurants per night of your stay (not one per day - one per night).
The Premium add on allows you to eat breakfast, lunch, and dinner per night at the same restaurants, but also includes the Park Hopper option and the Water Park Fun and More options, and includes unlimited use of selected recreation, admission to Cirque du Soleil® La Nouba™ and more.
The Platinum Package is everything the Premium package is PLUS pre-arrival planning service, a fireworks cruise, seats at Fantasmic!, certain spa treatments, room service, and the opportunity to dine at Victoria & Albert's.
But you will pay an arm and a leg for all that stuff. Don't forget that the MYW Plus pack including Park Hopping and the Water Park Fun and More is available for FREE for travel Jan - March.
EDIT: The counter service meal includes entree, dessert or one complete combo meal, and non-alcoholic beverage, and the table service meal includes appetizer, entree, dessert or full buffet and non-alcoholic beverage as well as gratuity. Children 3 - 9 must choose from children's menu if available. Also, no alcohol is served anywhere in the Magic Kingdom.
