We just got back from an 8 day stay at Boardwalk Villas. While there we tried Flying Fish, ESPN Club, Captain's Grille and last trip we also ate at bluezoo.
Flying Fish and bluezoo are fairly expensive but depending on how much you eat (apps, entrees and desserts?), it's reasonable.
Captains Grille was great for breakfast. We did this one morning and did the all you can eat buffet. But they do also have an ala carte menu.
ESPN Club was MUCH better than either my fiance or I expected it to be. In fact, we ate there twice. One afternoon when we weren't in the parks, we stopped in and it was empty. Food was good, large and very reasonably priced. We went in later in the week around 10pm to watch a Cubs playoffs game and it was of course busy.
