Millab Seongsu pop-up interest centers on a dessert cafe near Seoul Forest that is set up for more than everyday bread and coffee. The official pages describe Millab Seongsu as a dessert edit shop at 28-19, Seoulsup 4-gil, Seongdong-gu, Seoul, with the main shop on the 2nd floor and separate areas for pop-ups and venue rental on the 1st-floor terrace and 4th-floor rooftop.12
That makes the Millab Seongsu pop-up cafe a useful address to understand in two parts: the regular bakery-cafe operation, and the flexible spaces that outside brands can use for temporary activations. The official English site presents the venue around bread, coffee, and pop-ups in Seoul, while also noting that there were no active pop-up schedules listed for the week of May 12-18, 2026.3
Millab Seongsu Pop-up Cafe Layout

The clearest way to picture Millab Seongsu is by floor. The 2nd floor is listed as the order counter and bakery area, while seating is available on the 2nd and 3rd floors. The 1st-floor terrace and 4th-floor rooftop are identified separately as pop-up and rental spaces, which gives the building a layered role: part dessert shop, part cafe seating area, and part event-ready venue.2
For visitors, this means the everyday cafe experience and any temporary pop-up activity may not be the same thing. You might be looking for bread, coffee, and desserts on the 2nd floor, while a brand event, class, or shoot could be using the terrace or rooftop if one has been arranged. The official venue page says the 1st-floor terrace and 4th-floor rooftop are available for outside brand pop-ups, shoots, and classes.4
Millab Seongsu’s regular dessert identity is also part of the appeal. The Korean official homepage introduces the shop as a dessert edit shop and lists signature items such as honey eclair, Millab latte, seasonal gift box, ggullab madeleine, and plain salt bread.1 Those menu names help explain why the space can work as a cafe stop even when no specific pop-up schedule is active.
One detail should be read carefully: the Korean homepage includes a prototype notice stating, in Korean, that the page is in Phase 0 and that real payment and real data are not involved.1 So it is better to treat fixed venue information, such as the address, floor layout, and visit guidance, as the most useful planning facts rather than assuming every displayed commerce detail is live operational data.
Location, Hours, and Visit Basics
Millab Seongsu is located at 28-19, Seoulsup 4-gil, Seongdong-gu, Seoul, with the shop listed on the 2nd floor. The English official homepage says it is a six-minute walk from Exit 4 of Seoul Forest Station, which makes it easy to place on a Seoul Forest or Seongsu cafe route.3
The official visit page lists daily operating hours from 10:00 to 22:00, with last order at 21:30.2 The provided official material does not give separate operating hours for a specific pop-up event, and it does not confirm an active pop-up schedule beyond the weekly notice for May 12-18, 2026. If you are planning around a temporary brand event, the available source-backed point is simply that Millab Seongsu has designated pop-up spaces, not that a particular event is currently running.
Parking is handled plainly in the visit guidance. The official page says Millab Seongsu does not have dedicated parking and directs visitors to a paid public parking lot 30 meters to the right of the building.2 For a neighborhood like Seongsu, where many visitors move between cafes, shops, and showrooms on foot, that is a practical detail worth noting before you go.
For brands, the rental page adds a little more structure. It gives the same Seoul Forest-area location context, notes the six-minute walk from Exit 4, and says the minimum lead time for rental inquiries is 14 days. Rental units are listed by day or week, with a maximum duration of 8 weeks.4 In other words, the pop-up side of Millab Seongsu appears to be organized as a planned venue-rental function rather than an always-on open market.
What the Pop-up Angle Means
The phrase Millab Seongsu pop-up can be a little broad, because the official information supports the venue’s pop-up capability more strongly than it confirms any single ongoing event. The most accurate reading is that Millab Seongsu operates as a bakery and coffee space while also offering dedicated areas for pop-ups, rentals, shoots, and classes.42
That distinction is helpful if you are searching in English for a Millab Seongsu pop-up before a Seoul trip. You can rely on the official pages for the address, access from Seoul Forest Station, general cafe hours, and floor-by-floor layout. For a specific collaboration, brand activation, or class, the provided material only supports checking whether an active schedule has been posted.
The online shop page also points to a broader retail direction. It says Millab Seongsu plans to package store signatures and seasonal limited lines by box for delivery, with an official schedule listing a May 2026 seasonal box, June single-item line, and July goods and gifts. Delivery is described as CJ refrigerated delivery within 48 hours, while pickup is listed as same-day pickup at the 2nd-floor counter.5 That is separate from the physical pop-up spaces, but it fits the same pattern of a dessert brand using multiple channels.

Quick FAQ
Is there an active Millab Seongsu pop-up schedule?
The official English site listed no active pop-up schedules for the week of May 12-18, 2026.3 The source material confirms pop-up-ready spaces, but not a specific active event beyond that notice.
Where are the Millab Seongsu pop-up spaces located inside the building?
The official visit page identifies the 1st-floor terrace and 4th-floor rooftop as the pop-up and rental areas.2 The 2nd floor is the order counter and bakery area, with seating on the 2nd and 3rd floors. Millab Seongsu is best understood as a Seoul Forest-area dessert cafe with a built-in venue function. If you are visiting for bread, coffee, or signature desserts, the official pages give clear basics; if you are looking for a pop-up, the most reliable source-backed point is that the terrace and rooftop are designed for that kind of temporary use.
