I recommend Yonsei I-Rang Pediatric and Adolescent Clinic in Daehwa-dong, Ilsan.

These days, busy places with many people are pediatric clinics. Here at Yonsei Children's and Adolescent Clinic, it's also a busy place. Although it's crowded and busy, the staff and doctors are all very kind. It's nice that they also see patients on Saturdays and Sundays.

It's right in front of Daehwa Station, so it's easy to find, which I think is why there are even more people.

It's a good place except for the waiting time.
