Seongsu Dessert Park Popup: CU X RIIZE Turns a Dessert Convenience Store into a Fan Stop

CU Seongsu Dessert Park has become more than a dessert-focused convenience store this summer: it is also the setting for the CU X RIIZE popup running from June 20 to July 5, 2026. For anyone following Seongsu Dessert Cafes, this popup is a useful snapshot of how Seoul’s dessert scene, K-pop fandom, and convenience-store culture are now meeting in one compact space.¹

The location itself matters. CU Seongsu Dessert Park opened in Seoul’s Seongsu-dong on February 12, 2026 as a dessert-specialized CU store, with BGF Retail describing it as a 120-square-meter shop that expanded its dessert assortment by about 30% compared with a standard convenience store.² That foundation makes the RIIZE collaboration feel less like a random event and more like a pop-up layered onto a store already built around sweets, browsing, and small discoveries.

Inside the Seongsu Dessert Park Popup

The CU X RIIZE popup is centered at CU Seongsu Dessert Park in Seongdong-gu, with BGF Retail’s official X account listing the address as 21 Yeonmujang 3-gil, Seoul, and the operating period as June 20 to July 5, 2026.³ Since July 3, 2026 falls within that window, the event is still active, but only for a short remaining stretch.

The collaboration is built around RIIZE’s character brand “Little RIIZE.” CU introduced six collaboration products using the characters, including bread, macarons, and candy, with the items released sequentially.¹ The popup also includes a message zone and an event in which purchasing customers can receive Little RIIZE pin badges, giving the store a fan-gathering function beyond everyday snack shopping.¹

That fan activity has already been visible in coverage from the site. Kyunghyang Shinmun reported on June 22, 2026 that fans were exchanging collectible stickers included in RIIZE collaboration bread at CU Seongsu Dessert Park on June 21.⁴ For K-pop fans, that small detail is important: the appeal is not only buying a limited product, but also the familiar ritual of collecting, comparing, and trading.

CU’s broader reading of the moment is also telling. A CU representative was quoted as saying that “Korean convenience store culture itself can be seen as having established itself as a new tourism item.”⁴ In a neighborhood already associated with cafes, popups, and trend-driven retail, the convenience store is being presented as part of the itinerary rather than just a stop for necessities.

Why a Convenience Store Fits Seongsu’s Dessert Map

CU Seongsu Dessert Park was designed from the start to feel different from an ordinary convenience store. BGF Retail’s launch materials described curated zones featuring items such as Yonsei Milk cream bread, Dubai desserts, Bakehouse 405, and fresh fruit sandwiches, along with a DIY experience zone.² Goodkyung’s opening-day report also described dessert-zone items including Yonsei cream bread, the Dubai series, fruit sandwiches, and Bakehouse 405, as well as a DIY area with a whipping machine and toppings.⁵

That setup explains why the popup fits the space naturally. A fan can come for RIIZE collaboration products, but the store’s wider dessert assortment gives the visit a second layer: browsing sweets, choosing a drink, or looking around the curated dessert sections. Goodkyung also reported that bakery and coffee companion purchases accounted for 58%, a figure that helps show why dessert and beverage pairing is central to the store’s format.⁵

BGF LIVE described the store as “Dessert Blossom CU Seongsu,” connecting CU’s dessert lineup with a planned spatial experience. The magazine highlighted exterior design elements such as curved boards and pastel tones, plus a DIY zone and photo zone.⁶ In other words, the shop was not only stocked differently; it was also styled to encourage photos, sharing, and a slower kind of convenience-store visit.

One BGF Retail strategy MD team lead, Jeon Min-jun, framed the idea directly: “We wanted to show CU’s dessert competitiveness not only through products, but also together with space.”⁶ That quote neatly sums up why this store is relevant to the wider Seongsu dessert conversation. It treats dessert retail as something visual, participatory, and social.

What Makes the RIIZE Collaboration Stand Out

The RIIZE popup adds a clear fandom angle to a store already designed for dessert discovery. The reported sticker exchanges around collaboration bread show how a packaged dessert can become a collectible object when linked to a K-pop character universe.⁴ For visitors who care about limited goods, that may be the main draw; for dessert-focused visitors, the collaboration products sit alongside the store’s broader sweet lineup.

The international angle is also part of the story. Kyunghyang Shinmun reported that foreign customers accounted for more than 30% of sales at the store.⁴ That figure helps explain why CU and Seongsu are leaning into concepts that are easy to understand visually: character packaging, photo-friendly zones, limited products, and small take-home items.

Still, the most useful way to understand the popup is not as a replacement for Seongsu’s independent dessert cafes, but as a parallel form of dessert culture. It is fast, packaged, brand-driven, and fandom-aware. In a neighborhood where people often move between cafes, shops, and popups, CU Seongsu Dessert Park gives the convenience store format a more curated role.
