For 2012 there are new restaurants from the Downtown Disney area added to the Disney Dining Plan.
For a quick service credit you can go to:
Bongo’s Cuban Cafe Window, Cookes of Dublin, Earl of Sandwich, Marketplace Snacks, Pollo Campero/Fresh A-peal, Wolfgang Puck Express (my favorite).
For a Table Service you can try:
Bongos Cuban Cafe, Crossroads at House of Blues, Cap’n Jacks Restaurant, Planet Hollywood, Raglan Road, Wolfgang Puck Cafe, Paradiso 37, Portobello, Rainforest Cafe, and T-Rex Cafe.
For 2 table service credits you can try Fulton’s Crab House (highly recommended) and Wolfgang Puck: The Dining Room.
