This octopus restaurant is owned by FT Island's Min Hwan's uncle, which is located near Gumcheon-gu. You'll be able to see walls covered with Ft Island pictures. There's also a drum in the corner that Min Hwan used and gifts from his fans. This restaurant is not only popular among his fans but also among local Koreans because of its unique and delicious meal. A very reasonable price is a plus.
