Specifically what the law states is that you cannot carry in "any portion of the permitted area of an establishment that has been granted a Class A general retail permit as defined in part II of Chapter I or part I of chapter 2 of Title 26 of louisiana Revised statutes of 1950 to sell alcoholic beverages for copnsumption on the premises."
So basically you can enter the casino, but not an area where you can consume alcohol. Since this is usually anywhere in a casino, my judgement says you would be violating the law carrying inside at all.
In general, where I live in Louisiana, the proximity to a drinking establishment and the violation of this law is at the discretion of the judge. Most people I know who carry simply do not go to restaurants that serve alcohol at the table.
