It's a place I go to often because it's affordable. I bought a 3-session package for Pico toning, but the effect is minimal. I think you need to get it several times.
The facilities are clean and nice because they built a new annex, but there are too many foreigners and the wait is long.
It's right in the middle of Gangnam Station, so I often use it for Botox, Aqua Peel, and so on.
