You have to pay 20 dollars at ground floor in order to get to the bar and you get a voucher which you can use for drinks. If your drink is more than 20 you can pay the difference, plus
you are also charged for the service. Views are absolutely amazing - the bar itself is nothing special, been to better rooftops, but generally it was Ok. There was not enough seating space so we shared a tabele with a random couple, who turned out being very cool and we had a nice conversation with them so I m not mad at all about the lack of seating.
You pay for the view and the location really, but it s still worth it and better than spending money on a ticket to an observation deck.
