You should try the link to the Swan & Dolphin website on the resorts board. I think it is
www.swandolphin.com, and from there, click on the dining tab for descriptions.
The character buffet is at Garden Grove. We've only tried it during the w/e breakfast, but found the character interaction to be the best now available at WDW (probably due to the low crowd levels), and the food is quite good as well, comparable to Fresh at the Dolphin. Great Starbuck's coffee served at breakfast as well.
We have eaten at Garden Grove, Fresh, the Cabana, Il Mulino, BlueZoo, Shula's, and The Fountain. Would go back to any of them, and Il Mulino is now an every trip meal for us.
