This is The Drunken Admiral restaurant which we went to on one of our evenings in Hobart. It may have been the first night, I can't recall exactly.
However I do recall the interior which was very, very funky. It was organised into "decks" like the decks of an old wooden sailing ship, and with a skeleton attached to a wooden ship's wheel (helm) as the centrepiece.
The food was excellent as well.
I could have sworn that I took photos of the interior of that restaurant and its decor when we were there. And yet, I find no such photos in this directory. It's possible that I took them with whatever mobile phone I had at the time which means that they are the gods only know where.
It'll probably be easier just to go back there and get some fresh photos.
And some fresh fish for dinner.
