I ate at the Airport's restaurant.............don't recommend that one.............none of the various dinner offerings in the Magic Kingdom are mentionable, with the exception of the one in sleeping beauty's castle, and it had a few glaring flaws (portion size was one for me !)
If you aren't familiar with teh "Perkins" chain, I recommend the one on Space Coast Highway for breakfast........
And, being a big seafood fan, I would recomment the "All You Can Eat" seafood buffet at Boston Lobster Feast, also on the highway, if it's still there.
