In January, quite out of the blue it was open. Wasn't particularly busy so we're not sure why. After so many trips to WDW this was the first time we've seen it open so we had to try it. LOL
It was actually very very good but..........I placed my order, waited at the window, got my food...then the woman SHUT the window and closed the whole place down! Talk about timing..2 minutes later and we would have missed it AGAIN! LOL LOL
I hope you find it open on one of your trips. It was well worth it!
