You don't specify if you want resort or park dining. I know that some of the deluxe resorts(Poly/Contemp, Swan/Dolphin in the past) have multiple seating traditional Turkey day fair with all the trimmings. The park restaurants will stick to their menus. Go to wdwig.com and check out all the menus, if you don't want the tradional dinner. You will have to ask specifically at the hotels if they are doing a special meal. I'm not sure if Disney dining will know or not. Have fun!
