Located in front of exit 3 or 4 of Myeongdong Station. Just go down to Myeongdong Underground Shopping and you can cross to Myeongdong. At the left alley, Two two Chicken is a must try. At the right alley is the way to go to Namsan Cable Car.
The deluxe twin is a perfect choice if you are travelling in threes. The size is quite generous.
