## In short

T Coffee is a café on basement level 1 of the This Is Never That building on Achasan-ro in Seongsu, Seoul. Visiting alone, the writer ordered a cold brew and two sand cookies, and although T Coffee is underground, floor-to-ceiling windows bring in tree landscaping and sunlight so the room rarely feels closed in. For a quiet break from crowded Seongsu, T Coffee is most comfortable on weekdays after 4pm.

Looking for a café to relax in without the crowds of busy Seongsu? There are so many cafés in Seongsu, but if you show up on a weekend or during peak hours, it's actually not easy to enjoy a quiet cup of coffee. Crowded, chaotic...

The café I want to introduce today is T Coffee, a Seongsu café for people who want to spend time in a slightly more relaxed atmosphere instead of the chaos of Seongsu-dong. It's located in Seongsu, and the entrance is in the alley on the opposite side of the main road.

## Where is T Coffee in Seongsu, and how do you get in?

T Coffee is easy to find from the main street in Seongsu. The building it's in is the This Is Never That building, and on the basement level it's connected to Pizza Slice, so it's a great setup if you want pizza and coffee together.

## A basement café in Seongsu that doesn't feel closed in

What impressed me most about T Coffee was its basement location. Basement cafés usually lack natural light and can feel dim and stuffy, but this place has floor-to-ceiling windows showing the tree landscaping outside, and sunlight comes in well, so it almost never felt that way. The space is also well divided, so I didn't feel too self-conscious about other people looking over.

It seemed like a good spot to come alone to read a book or do some light work, and there were actually customers quietly spending time here.

## Is T Coffee good for a solo visit?

Above all, the atmosphere was great for visiting alone. The space itself felt cozy without being too cramped. If you're coming solo, it's a good place to order a coffee and read or just rest for a bit, and thanks to the quiet atmosphere, it also seemed like a solid option for those looking for a café in Seongsu to read in.

## T Coffee's menu: cold brew and two sand cookies

Since I was there to order, I checked the menu board. There was a good range of coffee and drink options — americano, cold brew, and so on — and you could pair them with a variety of desserts.

I went with the cold brew — rich, aromatic, and smooth enough that even I, someone who's not great with coffee, found it delicious.

After walking around all day I was a bit peckish, so I also ordered two sand cookies to go along with the coffee. The combination of rich coffee and sweet sand cookies was honestly perfect.

## Who should visit T Coffee in Seongsu?

- For anyone looking for a quiet spot to have a cup of coffee — Seongsu-dong is crowded with people even on weekdays!
- This is a café with real character that I'd highly recommend to anyone who wants pretty photos and a nice-vibe café for their feed.

A quick tip: if you visit on weekdays after 4pm, you can enjoy the café in an even more comfortable, uncrowded setting.
