Been to Garden Grove at the Swan several times now. For breakfast, it is one of the better options at WDW. A notch below Fresh at the Dolphin.
Dinner - been twice. Once for the Mediteranean (sp) night. It was good, not great, but solid. Just got back from trying the seafood night, and it was nothing memorable, maybe even disappointing. Some parts good, some not so much. We look forward to the Southern BBQ night in the future, but won't be back for dinner on those other nights anytime soon (especially not for seafood).
Dinner - bring your camera, b/c it is rarely crowded, and there are usually many visits by the characters.
