In short

How do you check reservations and the performance schedule?


You can reserve in advance through Naver Booking. Most weekday performances start at 8 PM and weekend performances start from 4 PM, though times can vary by schedule. I think it is best to check the day’s performance schedule in the News tab on Flat Nine’s Naver Place page before visiting and making a reservation.
A jazz dining restaurant close to Gangnam and Sinnonhyeon Stations
Flat Nine is a five-minute walk from Gangnam Station and a six-minute walk from Sinnonhyeon Station, so its location is quite convenient if you are looking for a Gangnam date spot or a restaurant for a Sinnonhyeon date.
Inside: bar tables and group seating

The restaurant has everything from bar tables to seating for several people, plus group seating for up to 24 guests. So it looked suitable not only for a Gangnam date with your partner but also for a small gathering.

Overall, the black-toned interior felt calm and refined, very much like a jazz dining space where you enjoy the music, food, and setting together. It was quiet and relaxed throughout, so it would suit a day when you want a meal that feels a little more special than usual, or when you are looking for an anniversary restaurant.
Base performance fee and course menus




There is a base performance fee of ₩15,000 per person when watching a performance. The course menus include the Classic, with Jeju black pork tenderloin steak as its main, and the Signature, with Korean beef 1++ striploin steak as its main. Cocktails not listed on the menu can be made on request, and there are non-alcoholic choices too—good news for lightweights!
The order of the Classic course
I ordered the Classic course meal so I could try the various dishes one by one~

When the course begins, an opening drink arrives first.

You can choose alcoholic or non-alcoholic, and I went with the alcoholic option. Made with cranberry, lemon, and mint, it was refreshing with a subtle sweetness—so tasty~

The first amuse-bouche was dauphinoise. It felt like having a very fancy hash brown! Its layered texture made it even crispier.

Next came focaccia with olive oil. The olive oil smelled wonderful, and with the simple focaccia, it was seriously delicious!

This was the accompanying squid-and-Korean melon carpaccio. I fell for the pretty presentation first, and the squid and Korean melon combination was new yet worked so well. The spicy sauce underneath, chewy squid, and refreshing Korean melon came together beautifully.


Then came the mille-feuille lasagna. Its stacked layers gave it lots of textures, and the crisp-baked exterior was especially appealing ❤️ The rich cheese flavor added to the ragù sauce made it delicious.


Finally, the main: Jeju black pork tenderloin steak! This was my top pick of the day ❤️ A green herb crust covered the outside, while the sliced pork showed a rosy interior, so the presentation caught my eye first. The black pork was so tender, with aromatic herb crust and mango purée creating layers of flavor.

Dessert was chocolate cake! It was a moist chocolate cake topped with house-made cream cheese and nutty nuts. Finishing with a sweet dessert made the whole course feel satisfyingly well put together.
The live jazz performance with dinner

One of the biggest reasons I chose Flat Nine was the live jazz performance. The Soyeong Quartet began at 8 PM that evening, and being able to hear live music right in front of me while dining was what set it apart from an ordinary Gangnam restaurant.
When calm, romantic songs came on, the romantic mood was absolutely overflowing, making it perfect for a Gangnam Station date with your partner. And when they sang upbeat, rhythmic songs, the atmosphere came even more alive and lifted my mood too.
There were piano and double-bass solo sections in between as well. It was not simply one vocal performance after another; there was time to focus on each instrument, which I think music lovers would enjoy even more.
I recommend Flat Nine for these occasions

Final thoughts: food and music in one place

Flat Nine felt less like a restaurant where you simply eat and more like a jazz dining experience where music, food, and atmosphere come together in one place. In particular, being able to enjoy a live jazz performance throughout the meal made it feel well suited to a date that is a little different from the usual. If you are looking for an atmospheric restaurant in Gangnam, a Sinnonhyeon restaurant date, or a Gangnam Station date spot, Flat Nine is worth adding to your list!
