For the restaurant No, but in order to buy drinks and participate in one of the 2 club areas, Yes!!
You do need to be 21. They ID you at the entrance.
They have a restaurant on the main floor. I assume you need to be 21 to go to the bar/dancing area but not 100% sure.
Not for the restaurant..but yes at the shows and in the club since drinks are served
Not to sit down in the restaurant
