It has been asked before but there was no clear answer. Is there an age requirement after 10 for people just going to eat?

Yes. After 10 pm, the kitchen is closed and no one under 21 is admitted

I would call to be sure I've never been in there that late. They serve food and it's a restaurant so should not be an age requirement.

No you r welcome

I would you call and ask. I didn't see any notice either

I did not see that posted anywhere when I was there recently.
