June 6, 2006. This is our Memorial Day trip. It was another holiday so of course everywhere you go, the place would be packed with people. This aquarium is just a small portion of the COEX mall. It's not big at all... especially when you're with 60 million other people. It has a lot of very interesting presentation: they've used a fake phone booth, some appliances and musical instruments to showcase their sea creatures. I didn't see them using a vault though, to house their W15800 entrance fee.
Take Subway Line 2 to Samseung Station. It's a long walk inside the mall but the signs to Coex Aquarium is very easy to follow.
