The main reason to ride Namsan Cable car is to get up the mountain faster. It doesn't offer any additional views that you couldn't get from walking up yourself, especially since, more often than not, the car is packed with so many people, all clamoring for a spot by the window. A claustrophic's nightmare! But if you're with family, young or old folks who can't manage the walk, or dressed up nice for the restaurant, it's definitely worth it. Myeongdong, exit 3, or better yet just tell your cab driver -- even in English, they all know this one.
