[Sports Seoul | Reporter Yoon Dong-eon] Mosu Seoul, the fine-dining restaurant run by Chef Ahn Seong-jae, has issued an official apology after a customer alleged they were served a different wine vintage than the one listed on the menu.
On April 23, 2026, the restaurant posted to its official social channels, saying it sincerely apologizes for the confusion caused during the wine-pairing service on April 19, 2026, and for not providing a clear enough explanation afterward.
The restaurant said it offered a private apology to the guest, who accepted it, but acknowledged that the response still fell short of what guests should expect from Mosu Seoul.
The controversy started with an online post by a customer identified as A, who said the menu listed a Château Léoville Barton 2000 vintage but staff served a 2005 vintage instead.
According to A, they noticed a difference in taste and aroma and asked staff to check. The sommelier reportedly confirmed the bottle was a 2005 and offered to bring the 2000 vintage separately so the guest could compare.
A also said staff later brought a 2000 vintage from another area and placed it on the table, which led the guest to wonder whether the restaurant knew the wrong vintage had been served from the start. The price gap between the two vintages was reported to be 100,000 KRW (about $75).
The guest criticized the response, saying it was hard to accept such a mistake from a two-Michelin-star restaurant, and that being told “we’ll let you taste it” felt like an inadequate substitute for a genuine apology.
Mosu Seoul is the restaurant where Chef Ahn—who appeared as a judge on the show Black & White Chef—serves as owner-chef. The dinner course is priced at 420,000 KRW (about $315). For two people with wine pairing, the bill can top 1,000,000 KRW (about $750).

Hello. We are Mosu Seoul.
We bow our heads and offer a sincere apology regarding the matter that recently surfaced on an online community.
On April 19, 2026, we failed to give clear guidance during the wine-pairing service, which caused confusion, and our follow-up response did not provide a sufficient explanation. We deeply apologize for the great disappointment this caused.
After the incident, we apologized to the customer separately, and they graciously accepted that apology. Even so, we take seriously the fact that our response did not meet the expectations guests place on our restaurant.
