Yongin City Yonsei Otolaryngology Clinic offers flu treatment on Sundays.

This hospital is open on Sundays during flu season, which is a huge help when you need urgent care. Since there's only one director, wait times can be a bit long when there's a surge in patients, but even considering that, I was overall satisfied with the treatment environment. The nurses and desk staff were all friendly and attentive, so I didn't feel uncomfortable or stressed while waiting. Even while waiting for my flu test, they checked on me frequently to make sure I was okay and checked my symptoms. I was also impressed by the care they gave the children, including Pororo candies. I'll definitely be back!
