This building also houses Khakis and thisneverthat clothing stores. T Coffee and a slice-pizza restaurant are on Basement Level 1, while the clothing shops are on the second and third floors, so it makes for a nice shopping route. It is especially worth stopping by if you are interested in the Khakis or thisneverthat clothing lines.

An open work space despite being underground

Although T Coffee is underground, its well-designed interior creates the wonderful openness of an outdoor terrace. There are table seats in several layouts. This is a café that welcomes people working on their laptops: nobody gives you looks for staying a long time, and everyone can work hard while drinking coffee. A real workaholic café, you could say.

Cakes and baked desserts

The dessert selection is nicely stocked, too. There are cakes and baked goods, with six kinds in all. Whatever you order, it is all delicious. These are not desserts that only look the part—you will be satisfied once you try them.

Morning coffee while the baby slept

With the daylight streaming in, morning is such a lovely time for coffee. My 17-month-old suddenly fell asleep, so we could not go straight to the art museum we had planned to visit and hurried over to T Coffee instead. In a way, it became a golden chance for me to relax and drink coffee alone.

Café latte and cheesecake

I ordered a café latte and cheesecake: ₩6,200 for the café latte and ₩7,500 for the cheesecake. They bring your order to your table. Made with a La Marzocco machine, the latte had a rich, deeply extracted coffee flavor.

The cheesecake was much tastier than it looked. Its texture and flavor were softer than an ordinary cheesecake, gently sweet and nicely balanced. It was lovely to spend a quiet moment at T Coffee in Seongsu with a light dessert and coffee.

Coffee and dessert enjoyed during a quiet moment

Whenever Hajun suddenly falls asleep while we are out, I always take refuge in a café. Once the weather turns chilly, I suppose I will not get to enjoy this little fun for a while.

A morning spent with latte and cheesecake

In the calm, restrained space of T Coffee in Seongsu, I had a nutty latte and cheesecake and spent Hajun’s blissful morning nap well. If you are looking for a café in Seongsu that opens in the morning, or simply a quiet café, stop by T Coffee.
