This is Odeng 오뎅. Although 오뎅 is originally from Japan, is also loved by many Koreans. As I posted earlier, you can eat 오뎅 at Po Jang Ma Cha 포장마차(especially with Ttuck Boy I 떡볶이), and 오뎅 바 odeng bar, and 분식집(sorry, no picture), etc.... Not only 오뎅 tastes good, but also soup of 오뎅 tastes good. If soup of 오뎅 is bad, 오뎅 tastes also bad. The hot soup of 오뎅 is very good in cold winter.
