Modern Bar Escape

You and your friends used to spend long time in this bar that is located in the heart of the city. You all left the city for various reasons and never got to be together for a very long time but finally the day for your reunion has arrived. You all have come back to the city after many years and you are all supposed to meet at the same bar. You mistakenly entered a modern bar and you are trapped inside that bar. You must come out from there as soon as possible and join your friends who will be waiting for you. All the best!
