Nothing happens there on Thanksgiving for customers. We were there Oct 2007 on Thanksgiving Monday for dinner, and only the servers and us had any idea that it was our Thanksgiving. The waiter did say, that they have staff only party with a turkey dinner once the restaurant closes for the day. No special decorations, no special additions to the evening menu, no mention of anything Thanksgiving!! I did have the best steak of my life here. ( I normally would not eat steak.) So it doesn't matter if you dine here on our Thanksgiving or another day on your holiday.
For a more Traditional Thanksgiving feast, I would recommend going to the Liberty Tree in MK. They serve turkey and the trimmings family style.
