Would like to go there for lunch when it opens at 12, I have an 18 and 16 yr old, is the 21 yr old limit enforced then?

They have a bar seperate from the gaming arcade, I don't see a reason why not.

I’d requested upon entrance, so no underage people allowed regardless of where you sit

Regardless of the venue no one under the age of 21 can sit at the bar But there is seating on the left hand side when you walk in Keep in mind this is bar this is a bar first
