Compiled from 20 blog posts read in fullSources →
A made-to-order lettering cake shop on the third floor of 409 Ttukseom-ro in Seongsu. Most people reserve a two-tier cake (cherry jelly or tiara) by KakaoTalk and pick it up; every post that names a price says 39,000 won. It also runs financier baking classes. We read 30 posts dated 13 to 30 September 2026; 10 were about the Apgujeong branch and were set aside, leaving 20 Seongsu posts, all from people who went in person.

Rows without a count: 2 of 10 posts.
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
- Of 18 posts that discussed price, 15 called it inexpensive. Nearly all make the same comparison: a two-tier cake at 39,000 won versus the usual 40,000-plus for a standard size-1 cake.
- Seven posts say there is somewhere to sit, not just a pickup counter: about three tables inside, or two two-seat tables plus one for three; one mentions a window looking out over Seongsu. One post calls the room small.
- Six posts say the cake was less sweet than expected and four say it was not heavy. Nearly every post lists the same build: chocolate sponge, Earl Grey cream, chocolate crunch, cream-cheese frosting.

Where it is
We could not find this shop’s own listing on Naver Map, so the link searches for its Korean name around this spot instead.
From the station
2 posts say it is walkable from the station.
Getting inside
| In a basement | yes 0 · no 4 (of 20 posts read) |
|---|
Four posts say the shop is up on the third floor, but none says whether there is a lift or stairs, or a step at the door. That means unknown, not absent.
No post says where the toilet is or whether it is split by gender.
No one mentioned: Second floor · Lift to the floor · Ramp at the door · Step at the entrance · Step-free access · Toilet inside · 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.

What we do not know
- Most cake posts repeat the same lines in the same order: unattended pickup until 10 pm, same-day cakes from 1 pm, Valrhona ingredients, the new Apgujeong branch. Three disclose sponsorship and the rest say nothing. We treat Valrhona, no-preservatives and 24-hour CCTV as the shop's own copy, not as evidence.
- Opening hours disagree. Eight posts say 10:00-22:00, but two give Tue-Fri 13:00-20:00 and Sat-Sun 13:00-18:00, one of them listing 10:00-22:00 separately as the unattended pickup window. Staffed hours and pickup hours seem to differ, so check before going.
- The only Seongsu prices are 39,000 won for a two-tier cake and 25,000 won per person for the class. Prices for single-tier and lunchbox cakes, drinks and cooler bags appear only in Apgujeong posts, so we left them out.
- Since cakes are reserved for a set time, no post mentions waiting; one says the cake was handed over straight away. Whether there is a wait to sit in is unknown.
- Seven posts give the number 0507-1329-8639, but everyone reserved through the KakaoTalk channel; whether phone booking works is unknown.
