Best Conference & Event Venues in Gangnam, Seoul (by Size)
Gangnam offers Seoul's widest range of event venues. Anchored by COEX, the district packs five-star hotel ballrooms, convention facilities, and seminar rooms into one area, with top-tier subway access and hotel infrastructure — making it especially strong for events with a mix of domestic and international guests. Here are Gangnam's standout venues, by size.
Why Gangnam
Gangnam is a rare district with three things at once: a deep menu of venues, excellent transit (Lines 2, 9, and Sinbundang), and surrounding hotel, dining, and parking infrastructure. Since most international attendees stay in Gangnam, hosting here keeps travel simple. The catch: as a prime district, peak-season booking is competitive.
Large (500–1,000+)
COEX — directly connected to Samseong Station. With convention, exhibition, and meeting space in one complex, it's the default for large conferences, trade shows, and international congresses. The Grand Ballroom seats up to ~900 theater-style.
Grand InterContinental Seoul Parnas — on Teheran-ro, connected to COEX. One of Korea's largest five-star hotel ballrooms (~1,160 capacity) with 12 combinable banquet rooms, ideal for large international conferences and award ceremonies.
Mid-large (300–500)
Signiel Seoul — atop Lotte World Tower, with Seoul's highest skyline views; strong for conferences and galas where premium positioning matters.
JW Marriott Seoul (Banpo) — near Express Bus Terminal Station, with a ~500 theater-style ballroom and five-star service for annual corporate events and ceremonies.
Mid-small & premium (100–300)
Josun Palace (Gangnam) — a Luxury Collection hotel with refined ballrooms and meeting rooms for VIP seminars and premium client events.
The Executive Centre (TEC), Gangnam Finance Center — advanced A/V as standard with on-site IT support, usable without membership; practical for corporate presentations, IR briefings, and small conferences.
Planning an event in Gangnam
- Parking & transit. Transit is excellent, but confirm parking capacity if many guests drive.
- Book peak dates early. Popular ballrooms sell out months ahead — even earlier during major weeks like KBW (September 29 – October 1, 2026).
- F&B minimums. Hotel ballrooms often carry an F&B minimum; compare on a total-cost basis.
