Last call 1:30 (Rivers choice, not mandated before 2AM). All drinks off floor by 2AM or 2:15AM(I don't remember). Security starts walking around telling you to finish it or toss it. I believe they start back up at 7AM.

The casino can buy a license to serve 24/7. I don't believe any casino in the state has done so. Reference: https://www.abc27.com/news/the-states-casinos-snub-new-law-allowing-24-7-alcohol-sales/
