I had a persistent cough, so I went to Yoon & Yoon ENT Clinic in front of City Hall in Dunsan-dong, Daejeon. Since it was a Saturday, the wait time was quite long, about 1 hour and 30 minutes, but I thought they had a lot of patients because they treated me so well. Dr. Yoon Won-jang's treatment was relatively thorough, and the director asked about my symptoms one by one and explained the cause of my cough in detail, which made it easy to understand. Please insert the endoscope into your throat and nose. I didn't feel rushed, so I didn't regret the wait as much. The prescription was good, and the staff at the desk were generally friendly. Considering the waiting time, I think I would visit again :)
