If I was hit with a Vodkabottle by a overserved patron in a overcrowed VIPsection of a club, is the bar liable?

Security was lacking and the bar failed to detain the suspects and call an ambulance. The VIP area was over capacity and most likely the opposing party was overserved and "hood". I have several problems with my face and brain after. Witnesses state I did not hit, nor instigate a fight. The opposing party did not pay for bottle service and were drinking out of our bottles I heard. What legal action should I expect?
