I would call the establishment rather than asking customers that question.
They have a banquet room downstairs that our dive club uses. There's a good chance that they will rent you that space if they don't have room upstairs in the main Pub.
You can reserve space for 2 hrs. Call soon to make reservation. It gets crowded soon.
I guess call and ask I doubt they would say no. The staff is super nice and flexible if you really need them to do that for you
