Mid-sized, ultra-modern venue. Saw Sigur Rod there (fantastic show) - but I am reviewing the venue, not the band.
Really modern, and clean. Entry is efficient and quick. Avoid the “cocktail” counter on the way in. We got Mojitos that were awful.
The venue itself is just a big box. There are large bars along the side, so getting a drink is quick and easy. There is seating at the back on two levels. I believe the whole place is general admission, so if you want a seat - you probably just need to get there early. We stood on the floor (which was totally fine - except when extremely tall Dutch people stand right in front of you).
Overall - it is a venue. A place to see shows of all kinds, and they do it well. Might not be for you if you need assigned theatre-style seating.
