Starting September 13,2021 you have to present proof of vaccination or a negative COVID-19 test before entering entertainment and recreational settings, restaurants and bars, or indoor gym and fitness facilities and group physical activity classes.

Proof of a US FDA or US FDA EUA approved vaccination administered outside the United States is not accepted for patrons/customers.
