Are they only open until 9pm? On their website is says midnight but google says otherwise

As of June 19, 2021, they have a sign posted 11am-9pm. I trust their physical location's signage.

They currently are only open until 9:00 p.m. . They're in the process of extending the hours but just have not done so, yet.

I think went i went it said 9pm at the entrance.

That is true atm.

I was there after 9pm one night a week or so ago. Hopefully they will go back to 11AM to 11PM Sunday through Thursday and 11AM to 12AM Friday and Saturday.

Trust their website.
