What is 7D ? How it works ? Lets check it out . To get this experience , we need to go to the excel world . This 7D hall contains 9 seats and there is a 3D glass for each and every seat as well as the seat belt . Its moving as the clip which we are going to see through the screen . Snows are falling , raining are common incidents in these type of halls . We can experience those also in this place . So I’m inviting you to visit Greentel’s 7D cinema hall which is in Excel world .
