Team Lunch in Seoul: Four Restaurants With Private Rooms
A team lunch is a harder booking than a team dinner. The window is fixed, usually the 11:30 to 13:30 rush; the headcount has to fit at one table; and the room has to be quiet enough that people can actually talk shop. Seoul has no shortage of good restaurants. It has far fewer that will hold a private room for eight people at midday on a weekday.
These four span City Hall, Euljiro, Seoul Station, and Apgujeong, and they are deliberately different animals: a hand-mandu house by Seoul Plaza, a 1956 Jung-gu institution with rooms upstairs, a window-lit Korean-fusion Western room near Seoul Station, and a premium Chinese dining room in Gangnam that seats up to sixteen. Each entry keeps the caveats from our research notes intact rather than smoothing them over, including which of them are on Chuseok holiday closures.
1. 진진만두 시청점 (Jinjin Mandu City Hall)
Jinjin Mandu City Hall is the City Hall branch of a hand-mandu chain (sister locations at Yeouido and the National Assembly) built around hand-made dumplings since 1998, tteokguk, and Pyongyang-style naengmyeon, positioned as a clean, modern-hanok-styled Korean restaurant for business lunches and presentable group meals steps from Seoul Plaza .

The most on-the-nose choice here. Jinjin's City Hall branch is a clean, modern-hanok Korean room steps from Seoul Plaza, positioned for business lunches and group meals that need to look presentable. The private rooms come with air conditioning and bag storage, and the kitchen has been folding mandu by hand since 1998, alongside tteokguk, Pyongyang-style naengmyeon, and suyukgomtang. Two things keep it from being effortless: lunch runs high for the category, and the room is a separate charge you have to request by name.
- Positioned as a clean, modern-hanok Korean restaurant for business lunches and presentable group meals, steps from Seoul Plaza.
- Private rooms include amenities such as air conditioning and bag storage, and one visitor judged the room suitable for a work dinner.
- Arriving after 11:30am produces an immediate wait on weekdays, and one visitor found the Catchtable reservation window already sold out.
Current status is unverified in this session; our records show it open with private rooms as of 2026-09-07, but confirm by phone or Catchtable before fixing a date. Private rooms carry a separate 20,000 won room charge that must be requested explicitly. Lunch pricing is high for the category: two dishes totaled 55,000 won for one visitor, with individual items at 17,000 to 19,000 won. No dedicated on-site parking in the dense city-center area.

2. Buminok
Buminok is a Jung-gu noreo (old-school Seoul institution) founded in 1956 by a North Korean-born owner with ties to Bumin-dong, Busan, built around yukgaejang and beef-tripe yangmuchim, and used daily by Dadong/Mugyodong office workers as both a fast lunch counter and an evening soju-and-anju spot .

Buminok has been open on Dadong-gil since 1956, founded by a North Korean-born owner with ties to Bumin-dong in Busan, and the Dadong and Mugyodong office crowd still uses it both ways: a fast lunch counter at midday, a soju-and-anju room in the evening. The menu centers on yangmuchim (seasoned beef tripe), yukgaejang, and yanggomtang, served in an unpretentious, historic room, and the second floor is divided into private rooms of varying sizes. It is the plainest room on this list and the one carrying the most history. It is also the one most likely to hurry you along if you arrive without a booking.
- The second floor is divided into private rooms of varying sizes, used for company dinners and groups who reserve ahead.
- A four to six person business dinner or company gathering is one of the venue's primary documented use cases.
- Listed as an active restaurant on the official Visit Seoul tourism site.
Reservation is essential for the second-floor rooms; a walk-in at lunch peak risks a wait and fast turnover ill-suited to a lingering 회식. Closed Sundays, and the operator record shows closure on 9/24 and 9/25 for the Chuseok holiday. Service quality is inconsistent across recent reports, and parking is minimal; use public transit.

3. Jade & Water
제이드앤워터 서울역점 (Jade & Water, Seoul Station branch) is a bright, window-lit Korean-fusion Western casual dining spot inside the Energy Plus/BMW building near Seoul Station, run as a satellite of the Oksu-dong (옥수동) flagship that built its name on brunch and celebrity patronage . It positions itself as an all-day venue -- brunch, business lunch, dinner-with-a-view, and private-room group dining -- built around Italian-leaning pasta/lasagna dishes reworked with Korean flavors .

The brightest of the four, and the one with a view. The Seoul Station branch of Jade & Water sits inside the Energy Plus/BMW building as a satellite of the Oksu-dong flagship, and the all-day menu runs shrimp sando, kimchi fried rice, steak, lasagna, and Italian-leaning pasta reworked with Korean flavors, from a chef known from Netflix's Culinary Class Wars. The private room seats 8 to 10, with a marble-look table and its own window, which makes this the easiest pick to sell to a team that does not want another Korean lunch. One scheduling condition: plan it for dates after the holiday, since the operator record shows this branch closed 9/20 through 9/25 and reopening Saturday 9/26.
- Reviewers explicitly frame it as an office workers' lunch spot, with bright, unhurried seating and easy reservation through Naver and Catchtable.
- A private room seating 8 to 10, with a marble-look table and its own window view, is repeatedly cited as suited to company dinners.
- The room has notably wide table spacing that reviewers say lets diners talk without being overheard.
- Had recently opened as of March 2025 and quickly filled up with diners, which points to strong local popularity.
The live operator record shows this branch closed 9/20 through 9/25 for the Chuseok holiday, reopening Saturday 9/26; do not plan this week's 회식 here. Group capacity hard-caps at 8 to 10 in the private room; larger teams cannot be accommodated. Lunch last order may be as early as 14:30, and ordering is by table QR code rather than table service. No on-site parking; drivers must use nearby paid lots.

4. MUTAN Apgujeong Main Branch
MUTAN Apgujeong Main Branch is an upscale, celebrity-frequented Chinese restaurant near Apgujeong Station best known for a truffle-and-steak jjajangmyeon that has become its signature dish across TV features and blogger coverage . It is positioned as a "premium Chinese" destination rather than a neighborhood noodle shop, with continual new-menu rotation and seasonal ingredient use .

Budget first: signature dishes such as the steak truffle jjajangmyeon run 25,000 to 49,000 KRW a plate, so settle what the team is spending before you float this one. What the money buys is the largest documented room capacity here, good for 8 to 16 guests, inside an upscale, celebrity-frequented Chinese restaurant near Apgujeong Station. The truffle-and-steak jjajangmyeon is the dish it is known for across TV features and blogger coverage, and the kitchen rotates new menus continually and cooks to the season. It reads as a premium Chinese destination rather than a neighborhood noodle shop, which is the point if the lunch is really a thank-you.
- A company dinner or gathering of 8 to 16 guests works by reserving the private room in advance, and multiple sources flag it as a go-to for company dinners and year-end parties.
- Open daily 11:00 to 22:00 with no break time between lunch and dinner, last order 20:50.
- The dining room has noticeably wider seat spacing than typical trendy restaurants, which reviewers call conducive to conversation.
Pricing is high-end for the category, with signature dishes at 25,000 to 49,000 KRW per plate, so confirm the team budget. The private room requires advance reservation and is not a walk-in option. Most available reviews are Naver blog posts, at least one explicitly sponsored, so the uniformly positive picture may be promotionally skewed.

If the office is in the city center, Jinjin Mandu is the most presentable room and Buminok the one with more character, with a four to six person table as its documented shape. Jade & Water is the pick when the team wants a window and a Western menu, capped at 8 to 10 in the room. MUTAN is the one that scales to sixteen, at a price worth clearing with whoever is paying.
One process note applies to all four: reserve the private room in advance rather than walking in at the 11:30 to 13:30 peak. And confirm hours before booking anything over the Chuseok holiday, since Jade & Water is closed through 9/25 and Buminok on 9/24 and 9/25.
