This is a review of my visit to Yaksu Internal Medicine Clinic for an office worker health checkup. Perhaps because so many office workers pass through here, I was impressed by the overall efficient and well-structured system. What I was most satisfied with was that there was almost no waiting time. From appointment confirmation to basic tests and blood collection, each step flowed seamlessly without any delays. Even though I took time out of my busy work schedule to visit, I was able to complete the checkup very quickly. To be honest, the service from the medical staff and employees didn't feel particularly friendly... perhaps because they are dealing with a large number of people, the atmosphere felt somewhat mechanical and businesslike. However, they were not unfriendly or unpleasant in any way. I think it is the optimal environment for those who want to finish their tests quickly.
