I recommend Yonsei Bom ENT Clinic, which is kind and provides good treatment.

Yonse Spring ENT Clinic is well-known in the neighborhood for providing good medical care, and both the doctors and staff are very friendly.

They also provide good treatment for sinusitis and rhinitis, so there are always many patients waiting.

This is an ENT clinic I visit when I am sick because they prescribe medication properly without unnecessary treatments.

If I had to mention a downside, the wait times are a bit long and the waiting area is somewhat cramped.
