Looking for a quiet café in Seongsu on a weekend? Try T Coffee

I needed somewhere to sit away from the crowds on a weekend, so I went back to T Coffee (티 커피), a basement café near Seongsu Station. I'd gone to Seongsu with a friend and the crowds completely drained me, hahaha. On weekends Seongsu is packed everywhere, and lots of cafés have waits or are just jammed, so we really needed a quiet place to sit T_T Then I remembered a café I'd visited before and headed back after a long while!! That's T Coffee, a quiet café in Seongsu ☕️

Why I came back to T Coffee

This was my second visit to T Coffee in Seongsu. On my first visit the atmosphere was so nice and it was easy to talk with my friend, so it stuck in my memory. This time too I was looking for a quiet café where we could talk, so I went back!

Finding the T Coffee entrance: basement level

T Coffee is on the basement level, so first-timers need to look carefully so they don't walk past the entrance, haha. I'd been before, so this time I found it easily!!

You feel the calm atmosphere as soon as you walk into T Coffee~~ Getting away from the weekend racket of Seongsu was already healing, hahaha. When you come into a quiet space after being in a crowd, you just feel relaxed, right?!

T Coffee doesn't feel cramped and is neatly decorated overall! Even though it's in a basement, the landscaping you can see through the big windows gives it a surprisingly open feel!!

The lighting and furniture aren't overly flashy either, so it's comfortable to stay for a long time.

What we ordered at T Coffee and the prices

At T Coffee we ordered two drinks: an iced americano for ₩5,500 and a matcha latte for ₩7,300. Order done, just like that~~~

  • ☕️ Iced americano ₩5,500
  • 🍵 Matcha latte ₩7,300

There were desserts too and I was tempted, but we'd just stuffed ourselves with pork cutlets before coming, so we skipped them this time..T_T But I should've eaten less... sob, looking at the photos they look so good..

Iced americano and matcha latte together

Ta-da, an iced americano and a matcha latte!! Last time I had the lemon ginger sparkling, but this time I picked a coffee and matcha combo. Honestly, after walking around Seongsu so much I was craving sugar, so I wanted a sweet-bitter matcha latte.

Green matcha latte

Isn't that green color so pretty?! If you love matcha, try the matcha latte at T Coffee. We ordered one coffee and one other drink and shared them while chatting, which was perfect, hahaha.

I think a café being pretty matters, but a place where you can stay comfortably matters too. Especially when meeting a friend, a place that's good for talking is the best!!

Is T Coffee in Seongsu worth a return visit?

I'd remembered T Coffee from my first visit because it was quiet with a nice atmosphere, and coming back I liked it just as much!! Weekend Seongsu is full of people and every hot café is crowded, so sometimes a calm space like this is extra welcome, hahaha. If you want to chat comfortably with a friend or need a short break in Seongsu, I recommend T Coffee~~!!

Can you work on a laptop at T Coffee?

T Coffee also has seats with outlets, so it's fine for people looking for a place to work on a laptop. And if you're like me and prefer a quiet, relaxed vibe over a noisy one, give this quiet Seongsu café a visit :) I'll probably go again next time I'm in Seongsu and think of it 💚
