I've been going to CHA Hospital in Jamsil recently to prepare for pregnancy. This is my third visit. Every time I go, they're very friendly and explain things clearly, which makes it easy to understand. Since this hospital is renowned for its infertility specialists, even if you make an appointment, the wait can be long due to the high number of patients. Please note that waits can be up to two hours, especially on Saturdays. In my experience, I find it more convenient to see a doctor in the afternoon than in the morning on weekdays. There's also a pharmacy on the first floor of the same building, which is convenient. Compared to the CHA Hospital buildings in Gangnam or Seoul Station, it's relatively new, so it's clean and tidy. Parking is available in the underground parking lot.
