This is no ordinary subway stop. This was obviously crafted for the Olympic Games, with wide tunnels, Olympic designs, and connection to Olympic Park. I'm not saying you should come out here just to see this station, but if you're going through here anyways to go up the tower and see Olympic Park, let your experience start from the subways station. Some parts are pretty run down, but realize that the games happened a long time ago.
Note the blue interlocking rings around the ceiling lights. I thought that was a nice touch.
