Don't know much about it, but here's the character line-up a listed at wdisneyw.co.uk:
Baskerville's, Grosvenor Resort:
-Goofy (Regular, only at breakfast on Tuesdays, Thursdays and Saturdays)
-Pluto (Regular, only at breakfast on Tuesdays, Thursdays and Saturdays)
I did the Grovesnor character breakfast once, they put out a pretty good spread for breakfast (dinner isn't as good) our characters were Goofy and Chip and Dale. I think Chip & Dale are always there and then one other character, probably Goofy and Pluto.
I wouldn't recommend it over a Disney character breakfast, but maybe as a last day breakfast before going off to the airport, the food is good and it isn't all that busy so you should get alot of character time.
