Gamjungsun Project is a one-day baking studio up a stairway on Sangwon-gil, on the first floor above the street. You do not buy bread here — you book a slot, bake six financiers or madeleines yourself, and carry them out in a box you decorated while they were in the oven. The other half of the floor is an art studio, so painting and craft classes run alongside. It is called the Seongsu branch, but Ttukseom is the nearer station: two to four minutes from exit 3 or 4. Booking only, and classes start on the hour. The posts we read run from July 2024 to September 2026.

Counted from what bloggers wrote in their posts; we did not confirm it with the restaurant. Where the values differ, it may be a change over time rather than a disagreement, so we show when each one was written.
What sets it apart
- You cannot walk in. Twenty-two posts describe booking and paying ahead, through Naver or the Somssidang app. And the clock is strict: the door opens ten minutes before your slot (five posts), being more than ten minutes late can lose you the class outright (two), and classes begin exactly on the hour (four). Two explain why — several teams start together in one room. One writer notes that the booking is one experience per person, so a couple must book two; another that there are no refunds inside a week. Two turned up on a weekday afternoon to a full room.
- Every seat has a phone holder. Twelve posts mention it — after booking, the most repeated fact about this place, ahead of anything anyone says about taste or price. It is a gooseneck clamped to the bench, so you can film the whole thing as a timelapse. Five bring up the timelapse and three of them shot one; one writer calls the whole arrangement unexpectedly thoughtful. One writer's advice is to set it up before the class starts — do it mid-batter and the phone works loose and slides, and you lose the thread. One, offered all this, simply declined. Half the reason this place sells as an unusual date is here: what you take home is not the pastry so much as the footage of yourself making it.
- ₩19,900 is the base, and it has not moved in the twenty-five months we read — a July 2024 post and an August 2026 post give the same figure. Nine call it cheap; two call it dear, and the two disagree about why. One loaded on the extras, paid ₩38,000 for six madeleines, and concluded that buying them would have been better value. The other paid only the base and still did the arithmetic: six for twenty thousand is ₩3,300 each, and three or four thousand buys a properly made one at any independent café. The add-ons run anywhere from ₩2,000 to ₩6,000 depending on whose post you read, and two writers found them ₩1,000 cheaper bought with the booking than on the day.
- The name says Seongsu; the station is Ttukseom. Fourteen posts place it near a station and thirteen of those name Ttukseom — seven come out of exit 3, four out of exit 4, and one writer gives both. Five put it two minutes away on foot; from Seongsu station it is a ten-minute walk, say three. At least one person got this wrong in person: she set off for Seongsu, found the place was at Ttukseom, and wrote the way in — out of exit 4, back on yourself, into the alley until the sign appears. One lone post puts it across the road from the pop-up strip by Seongsu station, which fits none of the others. Four posts give the distance as 158 metres from exit 4, and two of those say nothing else about getting there — that line is lifted word for word from the shop's listing, so we have not counted it. Eight writers describe going up to the first floor; two nearly walked past the sign, and two found the stairs narrow and steep.
- What the teachers do is the same in every post; what people make of it is not. Everything is weighed out before you sit down (sixteen posts), the steps are called from the front (thirteen), the trays go in and out of the oven for you (four) and come back by number (five). Fifteen writers call them kind. Three are disappointed, and all three land on the same thing — nobody tells you why. One got the steps read out like a textbook, with no reason for any of them; one says there is no teaching at all, only a briefing; one minds that you leave without the recipe. A fourth suspects it depends on who is working that day.
- Three writers call it clean; four call it cramped or grubby. The cramped ones wrote years apart without reading each other — too many people for the room (July 2024), the space smaller than expected and the work area tight (July 2024 again), about twenty people in one undivided room with little elbow room (December 2025). Where session sizes are given they run: sixteen people, twenty people, five teams, four tables of two. The hardest words are in one December 2025 post: a corner of an art school converted into a kitchen, a washbasin and toilet dirty enough that she reckoned washing her hands made things worse, and an apron still covered in someone's paint. A July 2024 post independently complains about a dirty apron too. Against that, an August 2026 writer went in worried about hygiene and came out saying it was tidier than she expected.

Exactly one person parked a car here and wrote about it. Several posts carry a “no parking” line at the top, but that is lifted from the shop's listing rather than seen, so we have not counted it — the same goes for the Wi-Fi, corkage and group-booking lines that sit beside it. The only first-hand account is from a December 2025 writer who drove: there is nowhere to leave a car, so she used a parking app and put it in the office building next door, ₩3,500 for three hours. The other twenty-two walked. If you are driving, one person's afternoon is the whole of what we know.

Not one post says whether a wheelchair or a pushchair can get in. Nobody mentions a step at the door, a ramp, or a lift. What is certain is the stairs: eight writers describe climbing to the first floor, one calling the entrance stairway narrow, another narrow and steep enough to take carefully. How many steps, whether there is a handrail, whether there is another way up — nobody writes. That is an absence of reports, not an absence of access.
No one mentioned: In a basement · Lift to the floor · Ramp at the door · Step at the entrance · Step-free access · Accessible toilet · Separate restrooms. That is not the same as there being none — it means we could not confirm it. Worth calling ahead, and do tell us: we will put it here.

Posts that followed a TV spot
Of the 27 posts we gathered, 4 went up on a single day right after a TV spot and show no sign of a visit. They retell the broadcast, so we left them out of the counts.
We do not discard them. That a TV spot produced a burst of posts is itself something worth knowing about a place, and a star rating will not show it.

What we do not know
- Write a review on the spot and the packaging is upgraded. Nine posts say so: post a Naver receipt review, or an Instagram post or story, and the paper bag becomes a decorate-it-yourself lunch tin. One writer noticed that most people around her were doing it. This is worth holding in mind while reading anything written about this place — it is not sponsorship, but it is not nothing either. Two of the eight posts that declare they paid their own way also record taking the deal.
- Two posts declare a sponsorship. They went up three days apart in January 2026, both for the Santa Kitty madeleine, and in both the whole declaration is a single hashtag at the end — nothing in the body. Eight others state they paid for themselves; the remaining thirteen say nothing. Thirty posts matched this address, of which three turned out not to be about it at all (two are bakery round-ups that never once name the place, one is a listicle mentioning a different branch across town), and four more we left out of the count: three are Seongsu day-trip posts where this place gets a line and a link — one of them by the same writer, about the same visit, as a post we kept — and one gives an address, a station and opening hours that contradict every other post we have. So the denominator below is twenty-three posts, and twenty-three posts here means twenty-three different people.
- Five posts say celebrities have been here; not one of the five saw anything. All five name the same two idols and all five hedge the same way — she is said to have come, apparently they posted about it. Nobody reports a signed photo on a wall or anything else you could look at. So we have counted it as nothing at all — only recorded here that five people passed the same rumour along.
- Two posts mention the toilet. One establishes that it is inside — she was sent to wash her hands before starting and found it at the back. The other, describing the same room, found the basin and the cubicle filthy. Whether it is split by sex, and whether there is an accessible one, nobody says. Several writers were told to wash their hands before the class; four say where they did it, two at the toilet and two at a sink by the entrance.
- The opening time has moved. Four posts from July and September 2024 give noon to seven on weekdays, noon to half eight at weekends. One from March 2025 gives one o'clock. Seven from November 2025 onward give two. Two hours later across two years — though nearly all of these figures are copied from the shop's listing rather than observed; nobody watched the door open. Two writers mention closing days, and both say there are none. Since you only ever come at a booked hour, the time that matters is the one on your booking, not the one on the sign.
- How long it takes depends on whom you ask. The bookings are sold as sixty or seventy minutes; the posts that time it report forty minutes, about an hour, seventy to eighty, and a hundred (twice). The short ones were unhappy about it — one September 2024 writer's seventy-minute class was over in about forty, and a February 2025 writer felt hurried through a room built for baking rather than for enjoying it. The two who made Kitty madeleines, by contrast, lost a hundred minutes without noticing. The difference looks like it follows the menu, but no two posts time the same class, so we cannot say.
- It is called a baking studio and half of it is an art studio. Twelve writers noticed the teams beside them painting Bearbricks, twisting pipe-cleaner dolls or icing cakes. Only one post is actually about that side, so what we know about the painting classes is one person's afternoon. She took a ninety-minute Bearbrick class in March 2025 for ₩19,900, having gone in nervous because the reviews were poor; she got a short briefing and no teaching, and found ninety minutes short once the clearing-up had to fit inside it too.
- You do not queue here, you book a slot — which is why nobody reports waiting. Every mention of a queue in these posts belongs to somewhere else the writer went that day (ten to fifteen minutes at one rice-cake shop, a pork place, a gelato counter). The waiting that happens here is waiting at your seat for the class to start, or for the oven — "put on the apron at your place, wash your hands, sit down and wait", "pipe the batter into the tray, into the oven, and wait while it smells wonderful." What is tight is the clock. One writer copies the rule: you may enter up to ten minutes before your slot, and arriving more than ten minutes late may cost you the session. Another (July 2024), told she could go in ten minutes early, waited at the door until she could. Sixteen to twenty people work through a slot together — two writers counted, separately. And slots do fill: "I went on a weekday afternoon and it was full" (January 2025); "there were a lot of people in the slot we'd booked, packed, and the room felt small for the number" (July 2024). So the thing to check is not the length of a queue but whether the booking page still has a seat.
