I went during lunch time on a weekday and there were a lot of people. The waiting time wasn't that long, but there was a lot of quiet waiting time. I spoke with the counseling director and he said that the surgeries for February were almost fully booked. However, they said they could tell you the discount rate if you make a reservation with one spot left, but it felt a little burdensome. It felt a bit forced. The director seemed very busy, and it was nice that he said no when he said no. Taking Citi costs 10,000 won!
