Do they take reservations for Thanksgiving?

I don't believe it has ever taken reservations, Though they do have call ahead seating. You say you're coming and they'll put your name, next on the list.

Yes

For the past several years starting around Nov1 they Take a list that is like call ahead seating, but you should be there a bit before but they'll give you an actual time. Thanksgiving is amazing there we go every year

Call and make the reservation and you will have a definite answer to your question
