Has anyone been to this movie theatre in Las Vegas?

When I went to Las Vegas last month, my mom,sister,and cousins went to this movie theatre which they said made them feel like they were in a slasher movie. They went up a few floors,down 2 hallways, and into this scary parking garage and the elevator waas already open. They got in. A lady vooice came over the intercom system and was like "hello,hello is anybody there?" And then beep beep beep like a telephone receiver. The doors opened and my mom was freaking out like close the door! somebody's gonna kill us!haha. Thnx
