Am I Allowed to order dominos pizza

You can order and eat it outside but won't be allowed to bring it in.

Unlikely since they have food there. And since they make you wait outside now, You can send one person from your group party inside to buy food

probably not but you could talk to the manager when you get there.

Due to the fact that they sell food, you will not be allowed to bring outside food n Bev.

To be honest don't know but they have their own food in there
