So far the most modern arena I've been to. Totally beautiful interior, which the exterior facade does not say. I was there at a concert, but the ticket and security controls were smooth and quick. I just found the stupid payment system with the chips, which you can get in the arena at the machine either by cash or credit card payment. There 5 chips cost 15 euros and for that you could have got 2 large cups of beer, for example, where a cup costs 2 chips. A small mug would have cost 1.5 chips, I find it expensive for a long evening. Otherwise very comfortable leather seats, an air-conditioned arena and a good sound!
