No. The bar owner would be immune from any liability under the anti dram-shop law, if your state has it on the books. In Louisiana, bar owners are immune from any tort liability related to the consumption or service of alcohol. They cannot even be held liable for DUI related accidents.

For immunity under the anti-dram shop statute to apply: (1) the bar owner must hold a permit to serve alcoholic beverages; (2) the bar owner or its personnel served alcoholic beverages to a person over the lawful drinking age; (3) the purchaser suffered and/or caused another to suffer an injury off the bar's premises; and (4) the injury was caused by the purchaser's intoxication.
