The ticket price was ridiculous (160 kroner = $28!).
There is no welcome movie/screen where you can watch something.
The restaurant was horribly overpriced and there was a queue half a km long for it... and it's the only place there where you can buy food. no sandwiches, no vending machines, no, you have to buy their overpriced fish n chips (120kr!), and needless to say, drinks are a rip off too. At least they provide free bread though. Only one (v expensive) eatery in the whole place? Very cynical, preying on your captive clientele who have no other choice.
There is nowhere to just sit down. They make all this fuss in the marketing about being "northern Europe's biggest aquarium" but the place feels small, stuffy, and cramped. There is nowhere pleasant to sit down, eat a packed lunch with your family, and let the kids run around (that wouldn't make any money would it?)
The area to watch the sea lion outdoor training is tiny, and designed horribly (like the rest of the aquarium... another landmark modernist architectural 'statement' that doesn't feel nice to be in, but looks great in photos) so that nobody can see anything.
Finally, the fish: beyond a few cool tanks with (very) small sharks, sea lions... and .. oh yeah, actually there are only 2 cool tanks there.
I've been to a real aquarium: in Genoa, Italy. It's the biggest in Europe, and that is what I call a real aquarium. This was a depressing, corporate, soulless experience but at least I could leave after a few hours. Poor fish.
... and if you insist on visiting, then please, do not, I repeat: DO NOT go on a saturday!!
