I had time to visit a new neighborhood called Nampo-dong, a shopping area on the south side of Busan. Nampo-dong has both normal stores and street shopping stores (think real and fake Nike).
Nampo-dong also has an observation deck called the Yongdusan park tower, it cost three bucks to get up there.
Here are some views from the top of the deck.
On this particular Sunday there was a dance party at the base of the tower, I think every kid in the photo below are trying to become a Korean pop star.
Also outside the tower was a large bell.
