I had a good night at the dogs after one game last season, we were a bit boozey and thought we would do something different, it turned out to be a proper good laugh, nice and easy to get a bus back into town then.
Depends what you are after. If you want a Stag do dressed in fancy dress and not giving a rats arse, head to west street I am pretty sure most places will accomodate you although you still may stuggle in a group of 12.
If you want to have a decent time I would suggest heading around the North...
