How about a private room restaurant near Jamsil Station for a couples' gathering?

We're a couple in our 30s looking for a relaxed place to have a meal in Jamsil, as we're going out alone for the first time in a while.

We'd prefer a spacious and comfortable room where we can focus on our conversation, rather than a crowded spot.

Are there any Jamsil Station restaurants with private rooms that would be suitable for a couple's meal, and also good for booking family gatherings of about 5 to 15 people later on?

We'd love to hear your real experiences about places where you could slowly savor the aroma and taste of the food in a calm atmosphere!
