Hongdae Hoshi Birthday Cafes 2026: Where SEVENTEEN Fans Gathered June 13-15

Hongdae Hoshi birthday cafes became one of the clearest fan-culture highlights around SEVENTEEN member Hoshi’s 2026 birthday. The available listings show a concentrated three-day birthday cafe period from June 13 to June 15, 2026, with Hongdae standing out as the biggest Seoul-area hub for fans looking for themed stops, cafe events, and commemorative perks.

For readers searching from a broader travel angle, this sits naturally beside the familiar idea of a Hongdae Tteokbokki Cafe route: a day in Hongdae can mix casual food, cafe-hopping, and K-pop fan events. The source-backed focus here, though, is narrower and more specific: Hoshi birthday cafe events in and around Hongdae, especially the venues and schedules that were publicly listed for 2026.

Hongdae Hoshi Birthday Cafe Scene in 2026

The strongest overall signal comes from Dukplace’s 2026 SEVENTEEN Hoshi birthday cafe map, which counted 29 active birthday cafes. Of those, Hongdae accounted for 19, followed by Busan with 4, Daegu with 3, Daejeon with 1, Changwon with 1, and 1 listed as other.¹ That distribution matters because it shows Hongdae was not just one possible stop; it was the main cluster in the available 2026 listings.

Birthday cafes, often shortened in Korean fan culture as “saengka,” are usually built around a simple but meaningful idea: fans gather at cafes decorated for an idol’s birthday, often with themed drinks, printed goods, small gifts, photo zones, or lucky draw-style activities. The source material does not provide one single standardized format for every Hoshi event, so it is better to treat each cafe as its own listing. Still, the repeated June 13 to June 15 timing across several Hongdae-related sources gives the 2026 Hoshi birthday cafe weekend a clear shape.

One named Hongdae listing was “SEE YOU SOON,” shown by Offmate with the address Seoul, Mapo-gu, Wausan-ro 29da-gil 14, basement right unit. The same listing page also displayed nearby Hongdae birthday cafe places such as “Waiting for the Summer You’ll Come” and “Superstar Kwon Sunbae.”² These names suggest that fans searching the area were not dealing with a single isolated event, but with a walkable neighborhood pattern of related cafe stops.

Named Events, Dates, and Cafe Details

Several individual cafes gave the 2026 Hoshi birthday period a more concrete schedule. Cafe Cherish announced through its official X account that its “2026 SVT HOSHI BIRTHDAY CAFE” event would run from June 13 to June 15, 2026. A separate notice from the same account listed operating hours from 12:00 to 18:00.³ For anyone planning around limited fan goods or cafe congestion, those hours would be an important practical detail.

Cafe2734 also posted a 2026 Hoshi birthday cafe event schedule covering both Seoul and Busan. The Seoul event was listed for June 13 to June 15, 2026, with Cafe2734 named as the venue; the Busan period was listed as June 13 to June 14, 2026.⁴ That Seoul-Busan split is useful because it shows the event was not only a Hongdae or Seoul phenomenon, even though Hongdae had the largest concentration in the broader map.

Another Hongdae source, Cafe Hannal Hanbit’s official X account, posted on June 15, 2026, that its birthday-day operating hours were 11:00 to 18:00. The same account’s event introduction showed the full period as June 13 to June 15, 2026.⁵ In other words, the birthday itself had an explicitly posted operating window, rather than leaving visitors to infer hours from the general event dates.

Dukplace also listed the Hongdae Hoshi birthday cafe “Hanip Convenience Store” as an event running from June 13 to June 15, 2026. Linked event information included the venue Mollis Picnic, first-come benefits, and lucky draw information.⁶ The available summary does not provide the full benefit list or draw rules, so it is best not to assume the exact items. What is clear is that this listing included the kind of limited fan-event mechanics that often make birthday cafes feel more like a small celebration route than a standard cafe visit.

How to Read the Hongdae Listings

If you are looking back at the 2026 Hoshi birthday cafe scene, the most reliable way to understand it is as a neighborhood cluster with multiple independent organizers. Dukplace gives the big-picture map and counts; Offmate gives a specific address for “SEE YOU SOON”; and individual cafe accounts such as Cafe Cherish, Cafe2734, and Cafe Hannal Hanbit provide event-period or operating-hour details.

That distinction is important. A map count can tell you Hongdae had 19 listed Hoshi birthday cafes, but it does not automatically mean every venue had the same schedule, perks, or crowd flow. Individual cafe posts fill in the practical parts, such as whether an event ran for all three days, whether June 15 had special birthday-day hours, or whether first-come benefits and lucky draws were mentioned.

For fans, Hongdae’s appeal is also easy to understand from the listings alone. With many venues concentrated in one area, it becomes possible to compare addresses, nearby cafe names, and operating windows before choosing a route. The sources do not state travel times, reservation rules, menu prices, or stock quantities, so those details should not be assumed. The confirmed facts are enough to show that Hongdae functioned as the main listed hub for Hoshi’s 2026 birthday cafe activity.
