It was opened every day except the last day during our 7/28/06-8/13/06 trip. The last day at MK 8/12/06 it was blocked with huge bushes and they were doing something with it. I just read another post that said they turned it into a buffet. This person said the CM said it was permanent.
The hours when we were there were for dinner open. Something like 4-9 or 5-8 or 5-9, something along those lines.
