Thomas Bakery Seongsu: A Tiny Vintage Cake Café in Ttukdo Market
Visit Thomas Bakery, a tiny vintage cake café hidden in Seongsu's Ttukdo Market: what to order, prices, opening hours, seating and its bigger second branch.
Why Thomas Bakery is worth finding
Most people come to Seongsu for its big warehouse cafés. Thomas Bakery is the opposite: a shop so small you could walk past it, hidden in an old covered lane of Ttukdo Market (뚝도시장), the traditional market at the quieter, southern end of the neighbourhood.
What stops you is the storefront. A pale grey wooden sign is painted by hand with THOMAS BAKERY, plus smaller notes: “fresh & sweet”, “Cake” and “North-2”. That last one is the shop's unit number in the market building (북2호). Below it, black steel window frames glow with warm lamplight, and a little hanging sign shows a running cat, which has become the café's unofficial mascot. Many Korean visitors say the place reminded them of a back street in Europe, or of a tiny café in Chiang Mai. Both comparisons make sense once you are standing in front of it.
What it feels like inside
Inside, it feels like someone's country kitchen. White enamel pots and jugs sit on open shelves. A framed embroidered sampler hangs above a table lamp, and a cloth bag dangles from a row of wall hooks. A glass showcase holds the cakes and white Thomas Bakery boxes, with a handwritten note taped to it saying the showcase keeps the bakery cold.
It is also genuinely tiny. There are just two small tables, and about four people is a full house. Visitors often wait a moment for a seat, sit for one coffee and a slice, then move on, while others pop in only for cake to take home. If you want a quiet, slow afternoon, come on a weekday soon after opening.
What to order
The shop focuses on cakes and bakes rather than bread. According to the owner, quoted by Korean visitors, the bakery lineup changes over time: some days bring something new, and existing cakes are tweaked now and then. These are the items listed on DiningCode, checked in October 2026:
| If you want… | Order… | Listed price |
|---|---|---|
| The house favourite | Extra virgin olive oil cake | KRW 4,500 |
| The photogenic one | Victoria cake (lettered “Thomas Bakery”) | KRW 7,200 |
| Something tea-scented | Earl Grey cake | KRW 7,200 |
| A classic | Homemade carrot cake | KRW 7,500 |
| Something rich | Dark chocolate cake | KRW 7,500 |
| Something fruity | Peach cream almond cake | KRW 7,500 |
| A warm-feeling snack | Strawberry or apple-cinnamon oatmeal crumble | KRW 5,800 |
For a first visit, I would get the olive oil cake. It is the cake visitors return for: soft, lightly sweet and not heavy, so it works even after lunch at the market. If you want the lettered Victoria cake for photos, go early; it is the most likely to be sold out. Visitors also mention scones and an almond and strawberry jam tart on some days.
Drinks are simple. There is one coffee, a black coffee (KRW 4,500), and no decaf. Visitors are split on it: some find it light, others oddly good with cake. If you are not a black-coffee person, the teas are a better match for the cakes: Earl Grey (KRW 6,000), peach & apricot (KRW 6,000) or rose (KRW 6,500). There is also a homemade lemonade (KRW 6,800) and apple or grapefruit juice (KRW 6,000 each). Drinks to go are KRW 1,000 cheaper.
Prices are from listings checked in October 2026, and Korean cafés update menus often, so the showcase and the counter have the final word.
Tips for your visit
- Arrive early for the full lineup. Popular cakes sell out, and a weekday morning is your best chance at a table.
- Plan to take cake to go. With two tables, a takeaway box is often the realistic option, and it makes an easy gift.
- Make it a Ttukdo Market afternoon. Eat at the market, then come here for dessert. Noppensan, a chai-only café, is a couple of minutes' walk away if you want a second stop.
- Keep your group small. Two or three people is ideal; a bigger group will not fit inside.
- Mind the door. It is an old shopfront, and visitors note the door does not always close by itself.
Getting there and opening hours
Address: 12 Seongdeokjeong 15-gil, North No. 2, Seongdong-gu, Seoul (서울 성동구 성덕정15길 12, 북2호), inside Ttukdo Market. Search 토마스베이커리 뚝도시장점 or the Korean address in Naver Map or KakaoMap; Google Maps is not reliable for walking directions in Korea. From Seongsu Station (Line 2), allow roughly 10–15 minutes on foot, and use live directions from your starting point. Inside the market, look for the grey hand-painted sign and the hanging cat sign.
Hours: The café's Instagram profile and DiningCode list 10:00–19:00, closed on Mondays. One visitor in spring 2026 noted 11:00–20:00, so hours have changed before. Check @thomasbakery_ on Instagram or Naver Map on the day you go.
Parking: None. Come by subway or bus.
Takeout: Yes, for cakes and drinks.
The bigger Seongsu branch
If the market shop is full, Thomas Bakery opened a second branch in early July 2026 at 430-1 Ttukseom-ro, 1F (서울 성동구 뚝섬로 430-1, 1층), about a seven-minute walk away. It has more room and adds brunch dishes such as cold pasta and a plate built on the olive oil cake, alongside the cakes. The original shop is the one with the photogenic storefront in my photos; the Seongsu branch is the easier choice if you want a proper meal or a seat for a group.
Who I would recommend it to
I would recommend Thomas Bakery to anyone who loves small, characterful cafés, to cake lovers who care more about the slice than the latte menu, and to anyone exploring Ttukdo Market who wants something sweet afterwards. Do not expect a place to linger for hours. Expect a few quiet minutes in a pretty little room, and a good piece of cake.
