Do I have a case??

Ok here's the situation, I was out for my work leaving do last Saturday, went to a nite club in town, (don't know if I should name it or not) anyway my girlfriend was in another club and was on her way over with another friend, also a girl and a random guy started talking to them but also following them.
When they got to the club they described this guy to the bouncer and told her not to let him in as he was following them.

When she got in she was really distraught and came over to me and a few friends, I asked what was wrong and she said that the bouncers let him in and he was right behind her. I approached him and asked him what he was doing and to leave her alone to which I got laughter in my face, at this time I raised my voice telling him to "**** off away from her" again laughter and a shove. I again told him to leave but he started saying abusive things towards her so I snapped and pushed him. A friend pulled me back which allowed him to punch me several times in the face. I responded with punches.

When the fight was broken up I was merely brought upstairs and cleaned up, it took a friend to convince the bouncer to ring an ambulance as I suffered a split chin, burst eye and broken tooth.

Seeing as I now have a dentist bill of €1,100 and am not working I have been advised to take action on the club (this was by a guard as I issued my statement) for not following their code of conduct ie: allowing him in and not calling the guards afterward.

Sorry for the long post
So what are my options??
