We went last October and enjoyed the meal. To me, it was similar to an Applebee's/Chili's type of place. The best part for us was that it's a quick walk from Epcot, and we got to spend some time walking around the boardwalk - we'd never been over here before, and it's fun to see.
As others have said, you have to call BRG directly, but you can get a reservation and they are part of the dining plan.
