Is this place usually busy on thankgiving day?

I would call ahead.

No idea. With that being a big Holiday they could be. Also after the last year they may shut down and let their employees have a day with family. The restaurant industry has been hit hard, no employees, means long hours 7 days a week. If you do go to a restaurant on a holiday please be kind. Have fun!!

Call ahead

I haven't been on Thanksgiving. It would be best to call ahead to find out.

Yes I've heard ...but not too crazy
