Yes you can file a civil lawsuit against the man that assaulted you and against the business, but you will have to prove the business liable for some civil tort or wrongdoing. Consult with a civil plaintiff's lawyer in your area to review.
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
