MARBLEJEONG Seongsu (마블정 성수)

MARBLEJEONG Seongsu (마블정 성수) is a premium Korean grill specializing in top-grade two-horn (투뿔, 1++) Hanwoo beef and wine-aged Korean pork. Located on the second floor along Seongsuil-ro, the restaurant has carved out a reputation as one of Seongsu's most ambitious meat destinations — a place where the cuts, the aging, and the service all point at the high end of the Korean barbecue spectrum. The two-horn Hanwoo grade is the top tier of Korean beef, marbled enough to render beautifully on the grill and tender enough to make the higher price tag feel reasonable for the right occasion. Alongside the beef, MARBLEJEONG offers wine-aged Korean pork belly that delivers an entirely different but equally premium experience — the wine aging mellows the pork's natural sweetness and adds a complex finish that pork lovers will recognize as a step above the standard samgyeopsal. The space is unusually large for Seongsu — large halls and multiple private rooms can accommodate gatherings of 100 or more, making it a popular pick for wedding-related dinners, corporate events, and family celebrations. Service follows the traditional Korean grill format with attentive staff doing the cutting and turning. With 173 Google reviews at a 4.9-star average, MARBLEJEONG has established itself among Seongsu regulars as the place to go when the occasion demands the best — graduations, anniversaries, or any night where the meat needs to be the main event. Note: there is a daily 16:00–16:30 break between lunch and dinner service.
