Seongsu café with a decaf mint latte and rare cheesecake: T Coffee
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.

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 :)

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~


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~


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 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🩷

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


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~👍🏻

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 👍


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!

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~


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?
