Seongsu café for a matcha latte and three-layer cheesecake: T Coffee

In short

T Coffee is a quiet basement café in Seongdong, Seoul, halfway between Seongsu Station and Konkuk University Station. Sitting just off Seongsu's main café street, T Coffee stayed calm, and a matcha latte at 7,300 won and a cheesecake split into three layers at 7,500 won balanced bitterness against sweetness. The matcha latte tasted sweet enough to suggest syrup comes as standard, so asking for less sweetness next time is the plan.

There are so many cafés in Seongsu, but sometimes when you actually go there are just too many people and it's too loud to relax. This time I went to T Coffee, a calm-vibe spot located halfway between Seongsu Station and Konkuk University Station.

A basement floor just off Seongsu's main café street

T Coffee is set a little away from Seongsu's main café street, and maybe that's why it had such a relatively calm atmosphere — I loved that. Even though it's actually underground, it felt clean and cozy rather than cramped.

You go down the stairs from the building entrance to reach T Coffee's space. You can also enter through the building and take the elevator! It has a clean, minimal feel, and I especially liked that it's a bit removed from the busy center of Seongsu. If you like the concept store Khakis in the same building, this café will feel familiar.

How big is T Coffee inside?

Once inside, the space was bigger than I expected. The overall calm mood made it feel fine for having coffee alone or chatting quietly. Personally, I was satisfied with how comfortable and restful the atmosphere was.

How did the matcha latte and three-layer cheesecake taste?

What I ordered at T Coffee was the matcha latte for 7,300 won and the cheesecake for 7,500 won.

The matcha latte had a mild matcha flavor that paired well with dessert, and honestly the matcha-and-cheesecake combo rarely fails. Pairing the sweet dessert with slightly bitter matcha gave just the right balance.

I think the matcha latte comes with syrup by default — it was pretty sweet. Next time I visit, I'll check if I can order it less sweet.

The cheesecake was also really delicious. It's divided into three layers, and the flavors were distinct!

When is the best day to visit T Coffee?

If you're looking for a slightly calmer, more relaxed space in Seongsu rather than a crowded café, give T Coffee a try. It's good for a quick break while hanging out in Seongsu, and it was a nice place to visit when you want to enjoy coffee and dessert in a quiet atmosphere. Next time, I'd like to try the coffee menu and the hand-drip too.
