On a weekday afternoon, I shared a matcha latte, café latte, and lemon sandwich with my sister amid spacious tables and big windows. Verdict: Come for the rich lattes and bright lemon cream sandwich. ## Good to know - **Address**: B1, 159 Achasan-ro, Seongdong-gu, Seoul, South Korea (서울 성동구 아차산로 159 지하 1층) - **Hours**: Mon–Fri 09:00–20:00 / Sat–Sun 11:00–20:00 - **Amenities**: Takeout, Wi-Fi, separate restrooms, and group seating - **Seating**: Group tables for about four people - **Order**: Matcha latte, café latte, and lemon sandwich *as written by the visitor on Sep 12, 2026* ## T Coffee, a break from Seongsu’s bustle I was in Seongsu-dong for an errand and happened to find T Coffee (티커피) just when I wanted to take a quiet little break! It is slightly removed from Seongsu-dong’s bustling streets, so it felt peaceful and laid-back. I also loved its leafy yet polished mood. It is a hidden Seongsu-dong café that is great for spending time alone or enjoying a quiet date. Head down to B1 and you will find the hidden T Coffee! The interior is super neat and comfortable. It is perfect for anyone looking for a quiet café in Seongsu-dong. ![Inside T Coffee on basement level 1](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-01-4aggk-900.webp) The stairs are steep, so be careful on the way down. There was also a pizza place right next to T Coffee. ![Steep stairs leading down to T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-02-1s0wc-900.webp) ![Pizza place near T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-03-1c9ua-900.webp) They sell simple yet luxurious-looking desserts, which are lovely with coffee. The coffee beans were wonderfully nutty and delicious, too. ![Coffee and desserts at T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-04-1nnzn-900.webp) ## A calm interior with big windows and spacious tables Carefully, carefully, I headed down to B1. The owners were really kind, and there were plenty of tables, so it did not feel crowded at all. There are quite a few group tables that seat about four people. The red table chairs were so striking. Although it is on B1, the full-height windows make it feel open rather than stuffy. ![Café interior with red table chairs](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-05-2kvcr-900.webp) ![Seating at T Coffee with large windows](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-06-iirjs-900.webp) It somehow captures Seongsu-dong’s hip vibe perfectly. It would be nice to have pizza first, then come here for dessert and coffee as a second stop. It is pleasantly quiet, and the big-window view feels cozy and warm. ![Inside T Coffee with a big-window view](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-07-3xwel-900.webp) ## Ordering matcha latte and lemon sandwich I ordered a matcha latte, café latte, and lemon sandwich. They also sell various sandwiches and scones. The desserts look refined in a way you do not easily see elsewhere. You absolutely, absolutely have to try the sandwiches. ![Matcha latte, café latte, and lemon sandwich](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-08-b2wgo-900.webp) Now I am curious about the chocolate sandwich, too. T Coffee really seems to be a sandwich-dessert gem, hahaha. The luxurious butter aroma hits you right away—it totally passed my taste test. ![Buttery sandwich dessert](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-09-1a5mq-900.webp) ![Sandwich dessert at T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-10-15q18-900.webp) The beans were very bold, so the latte was wonderfully nutty and rich :) Since it is underground, it feels like a hidden café known only to those in the know. The coffee is delicious, the desserts are delicious, and the atmosphere is good, good. I was happy to discover another new café in Seongsu-dong. ![Rich latte and dessert](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-11-175qq-900.webp) ![Café scene at T Coffee in Seongsu](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-12-dwmif-900.webp) ![Spacious tables at T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-13-9bobk-900.webp) And there really are lots of tables! I visited on a weekday afternoon, and I loved that it was not crowded. I wonder what the atmosphere is like on weekends~ There is a candle lit at every table, and the mood is so nice. It must create a different atmosphere in the evening, right? I think it would be wonderful for a date, too. The interior is very comfortable and tidy. It is the kind of café that makes you want to stay longer. Some people were working on laptops alone, and I think it would also be great for a private, uninterrupted date or a first date, haha. ![A candlelit table at T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-14-1yuzf-1200.webp) ## Clean matcha and tangy lemon cream The matcha latte, café latte, and lemon sandwich arrived. Once you are seated, the owners bring them directly to your table. ![Matcha latte, café latte, and lemon sandwich spread](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-15-1gl3z-900.webp) ![Drinks and lemon sandwich at T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-16-1f0vp-900.webp) The matcha latte did not have an artificial sweetness, so I enjoyed how clean it tasted. I do not like overly sweet drinks these days, and its clean matcha flavor suited me perfectly. The finish was pleasantly bitter yet clean! I loved that it did not leave a heavy aftertaste. The latte was also smooth and nutty, with rich coffee beans blending into the milk, and it went so well with the sweet-and-tart dessert. ![Matcha latte and rich café latte](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-17-aw1qp-900.webp) It was such a good place to talk that my sister and I chatted away for the first time in ages~ The drinks were delicious, and so was the lemon cream sandwich. ![Lemon cream sandwich dessert](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-18-uqtr9-900.webp) ![Sweet-and-tart lemon sandwich](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-19-nvk7a-900.webp) The lemon flavor burst through so brightly and the cream was so soft that my eyes went wide the moment I took a bite. The cream is wonderfully sweet and tart! If you like lemon, you have to try it. ![Sandwich filled with lemon cream](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-20-1n2az-900.webp) ![T Coffee lemon sandwich dessert](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-21-1ny35-900.webp) Not only was the interior lovely, but the coffee and desserts were so delicious that I was very satisfied! Next time, I want to try another sandwich dessert~ The latte was so good that I am curious about the other drinks, too. With calm music, delicious coffee and desserts, and a comfortable, open, spacious café, I got a proper bit of after-work healing before heading out. Among Seongsu-dong’s many cafés, this one feels especially cozy and special. ![Enjoying coffee and dessert at the café](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-22-w26uu-900.webp) ![Cozy scene at T Coffee](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-23-144lb-900.webp) It is the very definition of a luxurious sandwich. It is the sort of sandwich that makes you want to give it as a group gift, thanks to the premium butter they use, haha. The lemon cream inside is especially the star. It goes well with a sweet latte and with bitter coffee, too. You absolutely have to have dessert with your drink! ![Premium buttery lemon cream sandwich](https://img.superchart.com/images/seongsu-tea-coffee-lemon-sand/seongsu-tea-coffee-lemon-sand-24-16cdm-900.webp) It had been a while since my last Seongsu-dong outing, and it was a success as always, haha. If you are looking for a calm café with a lovely atmosphere and great dessert coffee in Seongsu-dong, I recommend T Coffee! ## Where it is - T Coffee (티커피) (티 커피) - B1, 159 Achasan-ro, Seongdong-gu, Seoul, South Korea (서울특별시 성동구 아차산로 159 지하1층) - 서울특별시 성동구 아차산로 159 지하1층 - 37.5433996, 127.0618187 - Google Maps: https://www.google.com/maps/search/%ED%8B%B0%20%EC%BB%A4%ED%94%BC/@37.5433996,127.0618187,17z --- Superchart · https://superchart.com/en/@paper-cup-routes/seongsu-tea-coffee-lemon-sand/ · https://superchart.com/llms.txt
