We had a group of 5 and sat at very comfortable table in the main dining room. We had asked for a quiet table, because we had members of our party who were hard of hearing. Sitting in the main dining room was perfectly fine. It wasn't too loud. I don't know about the bar area though.
The main dining room is very quiet. The tavern not so much.
I do not believe that there are small private rooms available but I would call and ask
