[Herald Muse=Reporter Kim Na-yul] Chef Ahn Seong-jae’s restaurant Mosu has apologized after a controversy over an alleged wine switch.
On April 23, Mosu posted a statement on its official channels addressing the claims.
Mosu said, “We offer our sincere apology for the matter recently reported.” “On April 19, during the wine-pairing service, we failed to give clear guidance to the guest, which caused confusion, and our follow-up explanation was insufficient, leaving the guest deeply disappointed,”
The restaurant added that it offered a personal apology to the guest after the incident and that the guest accepted it, but acknowledged that the response still fell short of what diners expect from their establishment.
They also said, “Chef Ahn Seong-jae and the entire Mosu team take this matter very seriously. We will review all related services and pledge to prevent a recurrence.”
Earlier, on April 21, a diner identified only as A said they ordered the wine-pairing set at Mosu but believe the restaurant served a different bottle than the one listed.
According to A, the pairing menu listed a Château Léoville Barton Saint-Julien 2000 vintage, but they were served a 2005 vintage that is about 100,000 KRW (approximately $75) cheaper.
A also wrote that the sommelier on duty did not apologize that day and criticized the restaurant’s handling of the situation. Online commenters slammed the response as inadequate for a two Michelin stars restaurant.
Meanwhile, Ahn Seong-jae is known for appearing as a judge on Netflix’s series “Black & White Chefs.”

Hello, this is Mosu Seoul.
We sincerely apologize for the matter that recently surfaced on online communities.
On April 19, 2026, during our wine-pairing service, we failed to provide accurate guidance to a guest, which caused confusion. We also failed to offer an adequate explanation in our follow-up response, and we sincerely apologize for the deep disappointment this caused.
After the incident, we apologized to the guest directly and they accepted our apology. However, we recognize that our response still fell short of the expectations you place on our restaurant, and we take that very seriously.
Chef Ahn Seong-jae and the entire Mosu team take this matter very seriously. We will review all related services and promise to prevent recurrence. We will not offer a perfunctory apology; we will act with sincerity to rebuild trust with our guests.
We apologize again to all our guests who have given Mosu Seoul their continued trust and support.
April 23, 2026
