The cleanest, most comfortable, and friendly ENT clinic in Jongno. My body aches weren't improving, so I went to Costco to shop, and then found the nearby Coco ENT clinic. Everyone was incredibly kind. There was a wait because it was a very busy clinic. Recently, they've been asking for ID for initial consultations, but they kindly told me I could use my health insurance app, so I was able to get in. The doctor who treated me was incredibly kind and explained my pain and symptoms. I also learned that the bronchial tubes are supposed to be translucent. He gave me excellent injections, and sometimes he misplaced blood vessels, but after a single injection, I felt my energy return. He even offered me water when I coughed. Everything was super clean.
