I have some great pics of my kids with Brer Bear at Goofy's Kitchen from last trip, too. August 2006. Come to think of it, we saw Brer Fox at Minnie's Breakfast at the Plaza, too.
You don't have to necessarily eat at Goofy's to meet him, if he's there that day. They have the photo area out front, and a character will be there for about 30 minutes. Then they switch them. That is the only place I have ever been able to meet Donald Duck, too.
Definitely ask at City Hall. And if they don't have info, ask if they can check if they are appearing in front of Goofy's Kitchen at all. They should be able to find out for you.
