Private Rooms in Jamsil, Seoul: 5 Picks for a Team Dinner
Jamsil is an office district and a convention district at once, which means the dinner that follows the day usually needs a door on it. The room decides how loud the table can be, whether the person at the far end can hear a toast, and whether the night reads as an occasion or as a crowded hall you happened to be standing in. The five places below all sit within reach of Jamsil Station, Jamsilsaenae Station, or the Lotte World Mall complex, and each one solves the room differently.
They also sit at very different prices, from a refill tuna house in the mid band to a course floor where dinner can reach 150,000 KRW a head. Booking works differently at each one as well, so the practical question is less which restaurant is best than which room you can actually hold on the night you need it. Everything below comes from our research notes on each place, caveats included, because rooms, minimums, and time limits are where a company dinner usually goes wrong.
1. Bloom in the Palace Lotte World Mall
Bloom in the Palace Lotte World Mall (동화고옥 롯데월드몰점) is an all-private-room, modern hanjeongsik (Korean court-cuisine-inspired course) restaurant on the 6th floor of Lotte World Mall in Jamsil, built around beef and noodle-centric royal-banquet dishes served as set courses . It functions as a special-occasion venue for families, couples, and business/formal gatherings rather than a casual walk-in spot .

The one place here where the room is not something you have to negotiate for. Bloom in the Palace runs entirely on private rooms, with no open dining hall at all, so the privacy holds whatever the headcount turns out to be. Naver Booking lists rooms for 2 to 16 people on the sixth floor of Lotte World Mall, some with a Seokchon Lake view. The format is formal and quiet: a modern hanjeongsik course built on beef and noodle dishes from the royal-banquet tradition, served as set menus, which is why reviewers keep pointing at it for the kind of company dinner that is really client entertaining. Catchtable lists lunch courses at 60,000 to 110,000 KRW and dinner at 90,000 to 150,000 KRW, rated 4.7. That dinner figure is the first thing to check against your budget. This pick leads the list because the privacy is guaranteed, not because it is the easy default.
- Every seat is a private room; there is no open dining hall.
- Naver Booking lists private rooms for 2 to 16 people with a Seokchon Lake view, on the sixth floor of Lotte World Mall.
- Catchtable lists lunch courses at 60,000 to 110,000 KRW and dinner at 90,000 to 150,000 KRW, rated 4.7.
- Multiple reviewers call the private-room format ideal for a company dinner, for formal client entertaining, and for meetings.
Dinner at 90,000-150,000 KRW per person may exceed a typical company dinner budget. The Seokchon Lake view is not guaranteed; request a terrace or lake-view room when booking. Parking is paid only, and the mall parking structure is reported as easy to get lost in.

2. Ichunbok Chamchi Jamsil Branch
이춘복참치 잠실점 is a room-heavy, all-you-can-eat bluefin tuna (참치) restaurant inside the Lotte Castle Plaza building at Jamsil Station exit 7, built around tiered refillable tuna courses and a large lunch menu of rice bowls, sushi, and soups . It functions as both a quiet business-lunch spot and a private-room venue for family celebrations and company dinners .
South Korea, Seoul, Songpa District, Olympic-ro, 269 2층 | $$
The classic Korean company dinner format, and the easiest room on this list to actually get. Ichunbok is a room-heavy, all-you-can-eat bluefin tuna house inside the Lotte Castle Plaza building at Jamsil Station exit 7, built around tiered refillable tuna courses, with a large lunch menu of rice bowls, sushi, and soups behind it. It doubles as a quiet business-lunch spot by day and a private-room venue for family celebrations and company dinners at night. Naver Booking has it at 4.52 across 1,782 reviews. Two things temper that, both stated below: the room is not automatic, and the refills do not hold their quality across a long night.
- Rated 4.52 across 1,782 reviews on Naver Booking.
A private room is not guaranteed without an advance Naver reservation; walk-ins may be seated in the noisier open hall. Refill quality in the all-you-can-eat tuna courses is reported to drop after the second round, which matters on a long 회식.

3. Nondureung Ori Jumulluk Jamsil Saenae Branch
논두렁오리주물럭 잠실새내직영점 (Nondurang Duck Jumulleok, Jamsilsaenae Direct-Operated Branch) is a large-format duck-jumulleok (spicy stir-grilled duck) restaurant near Jamsilsaenae Station, opened mid-2026 as a directly-operated branch of the Seolleung original . It positions itself as a group-dining, hoesik (company dinner), and family-meal venue built around a single core dish rather than a broad menu .
South Korea, Seoul, Songpa District, Baekjegobun-ro 9-gil, 23 1층 | $$
The pick when the team is large and the budget is ordinary. Nondureung is a large-format duck jumulleok house, spicy stir-grilled duck, near Jamsilsaenae Station, opened in mid-2026 as a directly operated branch of the Seolleung original and built around that one dish rather than a broad menu. Its room inventory is the best fit here for a big group: a dedicated group room plus a separate private-room option, bookings starting at 4 to 5 people, a larger group room taking 6 to 22, and group seating for 8 to 52. Reviewers frame the place explicitly as built for company dinners, citing those rooms and the wide table spacing, and the price point suits a standard company dinner budget. It stays on this list despite an incomplete verification pass, so read the first caveat and treat the room as a phone call rather than a booking.
- A dedicated group room and a separate private-room option exist for company dinners and family gatherings.
- Room bookings start at 4 to 5 people, with a larger group room for 6 to 22 and group seating for 8 to 52.
- Multiple reviewers explicitly frame the venue as built for company dinners, citing the private and group rooms and the wide table spacing.
Current status is unverified: verification this session found no reservation platform or booking policy for this branch, so its room must be confirmed directly by phone before planning around it. All reviews in our research files are 5-star or sponsored content from June to August 2026, so organic sentiment is unproven. On-site parking is disputed between sources; plan for public transport.

4. Mano Di Chef, Jamsil
Mano Di Chef, Jamsil is a Blue Ribbon-certified Italian restaurant in the basement dining arcade of Tower730 near Jamsil Station, positioned as a mid-to-upper-tier spot for dates, celebrations, and group meals rather than a quick casual bite . Multiple reviewers note it has held its spot for years while other tenants in the same basement food court cycled through, suggesting durable local demand .

The option when the group wants Italian rather than Korean. Mano Di Chef is a Blue Ribbon certified Italian restaurant in the basement dining arcade of Tower730 near Jamsil Station, positioned at the mid to upper tier for dates, celebrations, and group meals rather than a quick casual bite. Several reviewers note it has held its spot for years while other tenants in the same basement food court cycled through, which is its own form of evidence. It carries a dedicated room reservation product for company gatherings, and our check found it open with live booking on two platforms. Hours run Tuesday to Saturday 11:00 to 22:00 and Sunday 11:00 to 21:00, with a break in the afternoon. Read both caveats before you build a long evening around it.
- Open with hours Tuesday to Saturday 11:00 to 22:00 and Sunday 11:00 to 21:00, with a break time in the afternoon.
The room minimum spend and three-hour cap make it a poor fit for a 회식 that plans to run long or move into a second round at the table. Closed Mondays based on the listed Tuesday to Sunday hours.

5. Confier Selection
Confier Selection Lotte World Mall is a "casual fine dining" restaurant on the 6th floor of Lotte World Mall in Jamsil, built around a fixed multi-course French/Italian-leaning tasting menu (A/B/C signature courses) served at an open kitchen counter, tables, and bookable group rooms . Reviewers consistently frame it as an entry-level fine-dining experience at a mid-range price point rather than a top-tier destination restaurant .
300 Olympic-ro, Songpa District, Seoul, South Korea | $$$ | fine_dining, fusion
For a smaller team that wants a course without the hanjeongsik bill. Confier Selection sits on the same sixth floor of Lotte World Mall and calls itself casual fine dining: a fixed multi-course French and Italian leaning tasting menu, the A, B, and C signature courses, served at an open kitchen counter, at tables, and in bookable group rooms. Reviewers consistently place it as an entry-level fine-dining experience at a mid-range price rather than a top-tier destination, which is the right expectation to walk in with. The rooms come in two sizes, one for 4 and one for 5 to 10 people, with window views of Lotte World Tower or Seokchon Lake, and 4 is the floor: window tables and group rooms are not bookable below that. Plan the date early, for the reason in the first caveat.
- Bookable group rooms for 4 and for 5 to 10 people, with window views of Lotte World Tower or Seokchon Lake.
- Window-view tables and group rooms require a booking of 4 or more people.
Weekend group rooms need to be booked 1-2 weeks ahead; same-day booking is difficult. The tasting course is not served weekdays 14:00-17:00. Parking is not supported by the restaurant; mall parking fees apply.

One line each: Bloom in the Palace when privacy has to be guaranteed and the budget can take it, Ichunbok when the room has to be simple to book, Nondureung when the team is large and the budget is standard, Mano Di Chef when the group wants Italian, and Confier Selection when four to ten of you want a course.
Outside Bloom in the Palace, none of these rooms arrive with the reservation by default. Name the room when you book, by Naver booking, Catchtable, or phone, and do it before the invitation goes out. If you tell Concierge AI the headcount, the date, and the budget, it can narrow this to one and check whether that room is actually free: https://useconcierge.ai/
