I agree that the Boardwalk is the best option. We love the area because there are a lot of restaurants to choose from and you can either walk or take a Friendship boat.
If you're looking for a relaxing table-service without having to make an ADR, try the Captains Grille. The new Cat Cora restaurant, Kouzzina, is nice. For fine dining you could try Flying Fish or Yachtsman Steakhouse.
For more casual, you could try Beaches & Cream but they usually have a long wait. Either the Swan or Dolphin has a similiar burger place but I can't remember the name right now.
If you have a park hopper and walk all the way to Beach Club, it's not much farther to take International Gateway and pick up some fish and chips at the UK Pavilion in Epcot.
There are so many great choices, I'm getting hungry just typing this!
