Thanksgiving restaurant in Fairfax, VA area?

[DaisyDuck001]

Hi, I'll be visiting my father in the Fairfax, VA area for Thanksgiving. Looking for a restaurant with dine-in Thanksgiving dinner, either table service or buffet. I like the traditional Thanksgiving foods, but he is mostly vegetarian except he will eat fish. Does anyone know a restaurant in that area that will be open for Thanksgiving dinner and would have both types of food? If you've enjoyed a Thanksgiving meal there some previous year, that would be an even better recommendation. Thanks!
