Away from the busy main street, T Coffee keeps its tables in separated zones, so two friends can sit side by side over a matcha latte (7.3) and a nutty americano (5.5) and still hear each other. When Seongsu's crowds and waiting lines get tiring, T Coffee is an easy place to slow down. ## Good to know - **Location**: 159 Achasan-ro, basement level 1, Seongdong-gu, Seoul (488m from Seongsu Station Exit 2) - **Hours**: 09:00-20:00, last order 19:00 - **Coffee**: Americano 5.5 / Cold brew 5.5 / Latte 6.2 / Vanilla bean, almond or mint latte 7.0 (decaf, oat milk or soy milk +1.0) - **Non-coffee**: Matcha latte 7.3 / Vanilla chai tea 8.0 / Lemon ginger sparkling 7.5 / Lemon perilla mugwort tea or oolong tea 6.8 - **Dessert**: Sand cookie 4.2 / Pistachio cream choux 6.5 / Cheesecake 7.5 - **Seating**: Two- and four-person tables, one wide red table, separated zones - **Amenities**: Wi-Fi, separate men's and women's restrooms *as written by the visitor on Sep 4, 2026* ![Interior of T Coffee's basement café in Seongsu](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-01-18frn-900.webp) ## Where is T Coffee in Seongsu, and when is it open? T Coffee is a café at 159 Achasan-ro, basement level 1, Seongdong-gu, Seoul, 488m from Exit 2 of Seongsu Station. It's open 09:00-20:00, last order 19:00. I was in the busy part of Seongsu with a friend and we came here for coffee ☕️ Since it's tucked away from the main street in a quiet alley, it was relatively calm and nice. ![T coffee lettering on the window](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-02-1noxx-900.webp) The lettering on the T Coffee window in Seongsu was so cute ![Basement entrance in the same building as Pizza Slice](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-03-1w348-900.webp) It's in the same building as Pizza Slice, but on basement level 1, so you just head downstairs. Feels like a great route — grab pizza, then come straight down for coffee. ![T Coffee's dessert display case](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-04-8ncwk-900.webp) ## T Coffee menu and prices T Coffee had plenty of desserts, not just coffee. Sand cookie 4.2 ![Pistachio cream choux and cheesecake on display](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-05-1abkf-900.webp) Pistachio cream choux 6.5 / Cheesecake 7.5. The desserts looked delicious but we held off since we were saving room for a meal ㅠㅠ - Coffee — Americano 5.5 / Cold brew 5.5 / Latte 6.2 - Vanilla bean latte, almond latte, mint latte 7.0 (decaf, oat milk, soy milk +1.0) - Non-coffee — Matcha latte 7.3 / Vanilla chai tea 8.0 / Lemon ginger sparkling 7.5 / Lemon perilla mugwort tea, oolong tea 6.8 ## Why T Coffee's basement floor doesn't feel closed in Even though the café is on the basement level, it didn't feel stuffy or dark — the natural light was great. Most Seongsu cafés seem to just have views of people walking by, so this calm feeling was really nice, healing even. A café should be somewhere to talk and rest, but these days the busy Seongsu strip is all waiting lines and noise... it can be tiring. ![A T Coffee sticker my friend brought](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-06-g4uy4-900.webp) A sticker my friend brought because she thought it was cute haha, kind of unique and distinctive feel ![Open, spacious 4-person table area at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-07-1eru7-900.webp) ## Seats where two friends can sit side by side and talk T Coffee also has 4-person tables, so it seems fine even for a bigger group. It felt so open and had great vibes. ![Side-by-side seating at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-08-eh6oo-900.webp) The seats had different feels depending on where you sat, which was nice! We ended up sitting side by side like this, and it made talking easy. ![Drinks served in glasses at the table](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-09-4reb1-1200.webp) Staff brought the drinks over to us. The glasses were pretty too, and the atmosphere was great. ![Wide basement space connected to Pizza Slice](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-10-1feqa-900.webp) It felt connected to the Pizza Slice space like this, so it looked really spacious haha. There were also extra chairs you could grab and use! ![A cup of T Coffee's matcha latte](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-11-161eg-900.webp) ## How the matcha latte and nutty drip coffee taste T Coffee's matcha latte was also nutty and delicious. It had a rich, nutty matcha flavor that I loved. ![T Coffee's floor design](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-12-xjm1o-900.webp) The floor design was pretty too. ![T Coffee's dedicated entrance](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-13-7c9k2-900.webp) I didn't realize there was a separate entrance that leads directly into T Coffee! My friend and I were confused because we'd come in through the pizza place lol, but it seems like most people come in this way. ![Calm interior view of T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-14-7hdcz-900.webp) I really loved how calm and quiet this café was. Seongsu usually gets so crowded and loud that it drains your energy ㅠ but here we could just relax and chat over coffee! ![Divided table layout at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-15-l1xy7-900.webp) The tables were also spacious with the spaces divided up, which made it easy to talk, and there was good distance from other guests! ![A naturally lit seat at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-16-g8pzr-900.webp) ![Table and drinks at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-17-1r4hq-900.webp) ![Naturally lit seating inside T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-18-1yc8s-900.webp) ![Close-up of drinks on the table at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-19-1vthz-900.webp) ![Quiet seating area at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-20-1b60y-900.webp) The good natural light meant the photos came out great haha ![Coffee and matcha latte side by side at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-21-1cugl-900.webp) ![The nutty coffee bean choice at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-22-1bbia-900.webp) For coffee, there was a choice between a nutty type and a more acidic type — I went with nutty, and it was clean and delicious! Properly got my coffee fix. ![Wide red table good for laptop work](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-23-6fmah-900.webp) ## Laptop work, Wi-Fi and restrooms at T Coffee The red table was wide, so quite a few people were working on laptops there, and with a mix of 4- and 2-person tables, you could sit without worrying about space. ![Seating area with 2- and 4-person tables at T Coffee](https://img.superchart.com/images/seongsu-quiet-cafe-matcha-latte-t-coffee/seongsu-quiet-cafe-matcha-latte-t-coffee-24-f10ej-900.webp) Wi-Fi was convenient, the men's and women's restrooms were cleanly separated, and above all, it was a quiet, calm café — I loved that. ## Where it is - T Coffee (티 커피) - 159 Achasan-ro, basement level 1, Seongdong-gu, Seoul, South Korea - 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/@seochon-noon-bench/seongsu-quiet-cafe-matcha-latte-t-coffee/ · https://superchart.com/llms.txt
