Oh you're in for a treat. As previous posters mentioned, Disney Springs is just a smorgasboard of GREAT food - and many of the GREAT options are quick service so you don't need a ressie. Some of our fave sit-downs:
1. Wolfgang Puck - fantastic renovation, menu is strong just like the old Wolfgang Puck Cafe and excellent service.
2. Morimoto Asia - gorgeous indoor restaurant; possibly one of the best interior restaurant space in all of DS; food is delicious as well
3. Jaleo - Jose Andres should be a saint
4. Homecomin - huge DisBoard fave
5. Boathouse - another huge DisBoard fave
6. Raglan Road - fun times - especially if there's live music. Love the bread pudding.
7. I know there's more and I just can't remember... you really can't go wrong in DS. Never been, but Wine Bar George is usually waxed poetic on the DisBoards.....
Oh and don't forget... many of these restaurants can be reserved via OpenTable. So if you can't get a ressie through Disney, check OpenTable.
If you're craving your Beaches & Cream burgers & fries and shakes, D-Luxe Burger is a strong contender. Polite Pig is fantastic as well in the QS category. Ghiradelli and Everglazed has shakes.
I'm a huge dessert person so don't forget the sweets. Wolfgang Puck has a great cafe/bakery section. Sprinkles Cupcakes. Obv Gideon's - and walking over in the morning from SSR puts you right in the front of the line if you go when they open DS. Everglazed for donuts. Joffrey's vs. Starbucks, etc.
Honestly, DS has more (and better) options than your Beach Club/Boardwalk/Yacht Club circuit. DS is a quick 10-15 min walk from the center of SSR (The Springs section where the main building is). Have a blast!
