Terrible service, I think they advertise heavily to Chinese and hence wait room is overfilled with Chinese clientele who are very very patient in waiting for service. But for those used to western service, this is unbelievable - they made me wait 1.5 hours and when I finally saw the doctor, it wasn't the main doctor who's name is on the door, it was the intern doctor, and she didn't even do any of the analysis machines that were promised on their website. If you're used to having good and competent service for your dermatological needs, look elsewhere. So many good derms in Seoul, definitely don't go to this one.
