Ikseon-dong Mont Blanc Som: A Hanok Cafe Known for Chestnut Mont Blanc

Ikseon-dong Mont Blanc Som is a hanok-style cafe in Seoul’s Jongno district, best known in the available sources for its Bonuibam Mont Blanc dessert. If you are mapping out a dessert stop around Ikseon-dong, this is the kind of place that stands out for a very specific reason: a chestnut-focused Mont Blanc served in a traditional Korean house setting at 33-10 Supyo-ro 28-gil, Jongno-gu, Seoul.¹

The cafe is also listed in English travel information as Montblanc Som Cafe, a cafe and dessert spot about a three-minute walk from Exit 6 of Jongno 3-ga Station.² That makes Mont Blanc Som easy to understand at a glance: it is not just a general coffee stop, but a dessert cafe with a clear signature item and a location that fits naturally into an Ikseon-dong walk.

Ikseon-dong Mont Blanc Som and Its Hanok Cafe Setting

The strongest repeated detail across the sources is the setting. Triple describes Mont Blanc Som as a hanok cafe in Ikseon-dong, while several blog and travel sources place it at the same Jongno-gu address, specifically on the first floor at 33-10 Supyo-ro 28-gil.¹³ For readers unfamiliar with the area, Ikseon-dong is often associated with narrow alleys, converted traditional houses, and cafe hopping; within the facts provided here, Mont Blanc Som fits that pattern as a hanok cafe rather than a standard modern storefront.

A 2026 blog mirror entry describes the shop as having a hanok structure and a garden-style entrance, with ordering handled through a kiosk.⁴ That detail matters if you are planning a visit and prefer to know the basic flow before arriving. The same source says the Mont Blanc desserts are made after ordering, which helps explain why the dessert identity is so central to the cafe’s appeal.⁴

There is also practical support for visitors who may not read Korean comfortably. Triple notes that an English menu is available, and NOL World / Interpark Global likewise lists English menu availability for Montblanc Som Cafe.¹² Takeout is also listed in both sources, so the cafe is not presented only as a sit-down dessert stop.¹²

The Signature Bonuibam Mont Blanc

The main reason Mont Blanc Som appears repeatedly in dessert-focused sources is the Bonuibam Mont Blanc. Triple describes it as a dessert made by placing a paste of chestnut and cream on top of a cookie, and gives the price as 15,500 won.¹ NOL World / Interpark Global gives the same core description and the same 15,500 won price, reinforcing it as a key menu fact rather than a one-off listing.²

Other sources add more color around the chestnut theme. A December 2, 2024 article introducing four chestnut dessert cafes placed Ikseon-dong Mont Blanc Som under the theme of “Gongju chestnuts in Seoul,” and described the signature Bonuibam Mont Blanc as topped with bonuibam made from new-season chestnuts from Gongju.³ A Tistory post published on June 1, 2024 also described the Bonuibam Mont Blanc as using handmade bonuibam made with domestic Gongju new-season chestnuts, with the price again listed as 15,500 won.⁵

The wording varies slightly across sources, but the center of the dessert remains consistent: chestnut, cream, and a Mont Blanc format. Trip.com’s June 19, 2025 traveler post described the Bonuibam Mont Blanc as a menu item where sweet chestnut and bonuibam cream surround the cake, and it also listed the price at 15,500 won.⁶ If you are choosing one menu item based on the available information, Bonuibam Mont Blanc is clearly the most source-backed pick.

Menu Notes, Hours, and Visit-Friendly Details

Mont Blanc Som is not presented as a one-dessert cafe. Triple lists representative menu items including Bonuibam Mont Blanc at 15,500 won, black sesame cream latte at 7,500 won, and matcha strawberry Mont Blanc at 14,500 won.¹ The chestnut dessert roundup also says the cafe offers several Mont Blanc varieties, including bonuibam, matcha strawberry, and strawberry.³

Drink examples appear in travel and blog sources as well. Trip.com lists Americano at 5,800 won, Smith White Petal at 8,000 won, and Bonuibam Mont Blanc at 15,500 won in an example order.⁶ The Tistory post mentions Montbl Orange Ade at 8,000 won and Smithson White Metal at 8,000 won alongside the Bonuibam Mont Blanc.⁵ Because these are menu examples from individual posts, they are best read as helpful snapshots rather than a full current menu.

Operating-hour details differ slightly depending on the source. NOL World / Interpark Global lists hours as 10:00 to 22:30 with last order at 22:00.² Trip.com and the Tistory post list daily hours as 10:30 to 22:30.⁶⁵ Triple also notes last order at 22:00, which is the most consistently repeated closing-related detail.¹ If you are planning close to closing time, the source-backed point to remember is that last order is listed as 22:00.

Triple includes a few useful operating notes: some menu items may sell out early, each person is required to order one drink, and takeout is available.¹ Those details are small, but they shape expectations. A dessert that is repeatedly described as made around a signature chestnut component may not be equally available at every hour, and the one-drink-per-person rule is worth knowing before you sit down.

For anyone building an Ikseon-dong dessert route, Mont Blanc Som is easiest to understand as a hanok cafe with a highly specific chestnut dessert identity. Its Bonuibam Mont Blanc is the clearest highlight in the available sources, supported by repeated mentions of the 15,500 won price, the chestnut-and-cream composition, and the cafe’s Jongno 3-ga-accessible Ikseon-dong location.
