# Seongsu café with a decaf mint latte and rare cheesecake: T Coffee - By Moeun (https://superchart.com/en/@pastry-case-seat/) - Written Sep 1, 2026 - Local places › Cafés › Seongdong, Seoul - Sponsored: This post was written as part of a paid store-visit sponsorship. - English edition: https://superchart.com/en/@pastry-case-seat/seongsu-tea-coffee-decaf-mint-latte-cheesecake/ - Also in: [한국어](https://superchart.com/ko/@pastry-case-seat/seongsu-tea-coffee-decaf-mint-latte-cheesecake/index.md) ## In short T Coffee is a café and dessert shop on the basement level of a quiet alley building, a 5-minute walk from Exit 2 of Seongsu Station in Seoul. The mint latte costs 7,000 won, switched to decaf for an extra 1,000 won, and the 7,500-won cheesecake had a soft rare-cheese texture whose faint mint note matched the coffee well. With wide spacing between tables and a full-height window looking onto trees, T Coffee is a quiet Seongsu café for working alone or talking without raising your voice. ## Good to know - **Location**: 159 Achasan-ro, B1F, Seongdong-gu, Seoul (about a 5-minute walk from Seongsu Station Exit 2) - **Hours**: Mon-Fri 09:00-20:00 / Sat-Sun 11:00-20:00 - **Mint latte**: 7,000 won (decaf option +1,000 won) - **Cheesecake**: 7,500 won - **Dessert lineup**: Sand cookies, biscuits, three kinds of cheesecake - **Options**: Decaf and oat milk swaps available - **How to find it**: Right next to the pizza slice shop, basement level (B1) - **Price reference**: ₩7,500 ≈ $5.4 (2026-09-18) *as written by the visitor on Sep 1, 2026* ![Cover image of T Coffee café in Seongsu](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-01-1x1ex-900.webp) ![Atmosphere shot of T Coffee near Seongsu Station](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-02-t4thp-1200.webp) I found T Coffee while looking for a nice atmospheric café to work in near Seongsu Station! Seongsu cafés are usually so crowded and loud that I tend to avoid them, but when I was visiting the area recently and searching around, I found a genuinely great-vibe quiet Seongsu café, so I wanted to share it :) - T Coffee / 159 Achasan-ro, B1F, Seongdong-gu, Seoul, South Korea - ⏰ Hours: Mon-Fri 09:00-20:00, Sat-Sun 11:00-20:00 ![T Coffee's basement entrance in the alley](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-03-obia8-900.webp) ![Stairs leading down to the T Coffee entrance](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-04-owemh-900.webp) ## How to walk from Seongsu Station Exit 2 to T Coffee in 5 minutes I finally visited T Coffee, known as a quiet Seongsu café. It's about a 5-minute walk from Seongsu Station Exit 2, tucked in a not-too-crowded alley, so it felt calm and cleanly minimal right from the entrance! It's on the basement level (B1) and sits right next to a pizza slice shop, so keep that in mind~ ![T Coffee's ivory and wood-toned interior](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-05-1ctoe-900.webp) ![T Coffee seating with wide table spacing](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-06-j67qe-900.webp) ## Inside T Coffee: ivory and wood tones with wide table spacing Here's what the inside of T Coffee, a Seongsu café, looks like~ The interior is overall ivory and wood-toned, giving off a really clean feel, and it already had that great-coffee-spot vibe going strong haha 👍 The place was surprisingly spacious with plenty of seats! The tables were spaced quite far apart too, so it's good for chatting~ ![T Coffee seat with a tree view through the full window](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-07-1qe3v-900.webp) ![T Coffee's accent space with pretty lighting](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-08-1nno7-900.webp) ### A basement café with a full-height window and tree view Even though it's on the basement level, one side has a full window with a tree view, which gives it a really fresh feeling. There's also an accent spot on one side of the store that gave off proper Instagram-worthy vibes ❤️ The lighting is pretty too, so photos come out great~ Genuinely such a lovely, aesthetic café mood!!!💓 ![T Coffee's coffee and drink menu board](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-09-1jrmn-900.webp) ## T Coffee menu and prices: decaf and oat milk swaps Here's a photo of the T Coffee menu~ There was a wide variety of coffee and drinks, and it was even better that there were decaf and oat milk substitution options! For coffee lovers, this seems like a place you can enjoy in many different ways haha🩷 ![Dessert showcase with sand cookies, biscuits and cheesecake](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-10-hbph2-900.webp) The desserts felt minimal and clean too! 👏🏻 Displayed like this, the shapes looked so pretty! There were three kinds — sand cookies, biscuits, and cheesecake — and I went with the cheesecake~ - ✔️ Mint latte ₩7,000 + ₩1,000 for decaf option - ✔️ Cheesecake ₩7,500 ![Table setting with T Coffee's mint latte and cheesecake](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-11-12lsk-900.webp) ![Mint latte and cheesecake served in clean cups and plates](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-12-ulyhm-900.webp) I ordered the cheesecake and mint latte! Both the cup and plate were served with such a clean look that they matched the café's atmosphere perfectly~👍🏻 ![T Coffee's rare cheesecake with a crumble base](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-13-hl8qj-778.webp) ## What does the cheesecake at T Coffee taste like? The T Coffee cheesecake (₩7,500) had a soft, rare-cheese texture, and the crumble layer at the bottom had just the right thickness, which went well with the coffee 👍 ![Cross-section of the rare cheesecake cut with a fork](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-14-19b7p-900.webp) ![A bite-sized scoop of the cheesecake](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-15-1q2xx-900.webp) A rare cheesecake that cuts so smoothly with a fork..❤️ It was really sweet and nutty, genuinely delicious, and especially good when eaten together with coffee!👏🏻 It's sweet and tasty enough that if you like cheesecake, you really should try the T Coffee cheesecake! ![T Coffee's mint latte switched to decaf](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-16-18q7j-900.webp) ## How the mint latte tastes as a decaf The mint latte caught my curiosity the moment I saw the name, so I ordered it! It wasn't overly strong, but the mint aroma blended really nicely with the coffee, and it was subtly addictive~ ![Close-up shot of the mint latte cup](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-17-nbu3v-900.webp) ![Mint latte and dessert placed together on the table](https://img.superchart.com/images/seongsu-tea-coffee-decaf-mint-latte-cheesecake/seongsu-tea-coffee-decaf-mint-latte-cheesecake-18-16c1t-900.webp) If you're usually a fan of mint, this is a coffee you can enjoy in a special way! Living up to its name, T Coffee really felt like a café that's good at coffee, and I think I'll come back for a different drink next time I'm near Seongsu haha ## Who is T Coffee in Seongsu best for?
