Wife and I ate at Capn Jacks in Jan '05. Food was good, but nothing spectacular.
We had dinner at Fulton's on our honeymoon in Aug '03, and it was one of the best meals I have ever eaten. I had the filet mignon & lobster tail, both were excellent. Wife had the king crab claws and a filet, and still raves about the crab claws.
I have read a few bad reviews lately about Fulton's, but it still ranks up there w/ my best Disney meals ever.
