Often the Thanksgiving menus are not released until November. Nearly all full service and buffet restaurants offer one "traditional" entree for Thanksgiving. The "tradition" varies with the restaurant. One my have pumpkin brulee for dessert where the other will have fufu for a vegetable, that sort of thing.
Much would depend upon where you normally like to dine.
Many people love going to 50's Prime Time Cafe for Thanksgiving dinner.
