1인 전용 수 노래연습장 literally means singing practice room for 1 person. This place has 20 1-person-karaoke rooms, equipped with modern monitor, mike, and remote control. You only need to pay between 2000 KRW to 8000 KRW per hour to enjoy this place. You can also pay additional 1000 KRW for beverages in self-bar. From soft drinks to iced coffee, you can choose it.
It can be a nice place to relieve your stress, just singing your heart out like BEAST Yoon Doojoon and Lee Sookyung did in tvN drama Let's Eat (식샤를 합시다).
