I would be a little wary of "expecting" variations to the menus.
We ate at 1900 Pk Fare on Christmas Eve 2004, and although allears had posted there would be a "festive" selection" on Christmas Eve and Christmas Day, there was nothing different on offer. We werent bothered, as there was the usual selection of lovely dishes.
However, for Christmas Day, we especially wanted a turkey dinner in one of the nicer restaurants. I searched the net for menus and picked the California Grill, who where going to offer roasted turkey with yam mash and seasonal vegetables.
We were very disappointed to find that this was NOT on offer on Christmas day, and the server was quite rude when we asked about it.
Although the meal we chose was nice, it wasnt exactly what we wanted for that day.
Even the CM when I booked assured me that "ALL" the restaurants offer a festive selection over the holidays. Im afraid that isnt the case, so it may be wise not to get your hopes up too much.
Whatever you pick, I hope you enjoy it.
