5* for the amazing curved glass (which magnifies and let's you see the fish as if it was right beside you) and for the ingenious conveyer belt which you stand on so you can focus on looking rather than walking. :D
love love loved it. it's really cool that they are mostly all in one huuuuuge tank surrounding you (it's layout is like a huge huge tank and people walk In a tunnel carved from the tank, so you see fish above and beside you).
It's one of the few aquariums where you feel like you are actually in the water with the fish, rather than you just being an observer through a glass.
