A world of delicious desserts, Notldun

Is there a café you want to go back to right away? My first visit was already satisfying, but the second visit was even better, so I wanted to go back immediately — let me introduce this Seongsu dessert café.

605m from Ttukseom Station Exit 8. This is the exterior of Notldun on a weekday evening, around 7pm — I felt good even before stepping inside. This is a dessert café where anyone you bring will enjoy the food, and I honestly want to recommend the two dessert cakes I tried this time.

The store itself isn't huge, but I'd say it's worth waiting if it's full, and if you don't have time, definitely try takeout! My personal top pick is ✨Notldun's Signature Noir✨

Notldun is apparently marking the 40th anniversary of Valrhona's most iconic dark chocolate, 'Guanaja' — Valrhona being a premium French chocolate brand. These days I find myself only choosing good chocolate when I eat it, so knowing this place uses premium French dark chocolate Guanaja put my mind at ease!

Notldun is a dessert café with a truly wide variety on offer — just looking at the photos makes me happy. You could take any of these home, or they'd make a perfect gift too.

Notldun's Signature Noir

Notldun Signature Noir cake

Notldun's Signature Noir, ₩14,000. This was genuinely delicious. It's a dessert made with milk chocolate mousse, almond praline, whiskey cream, and crispy croustillant — you could call it Notldun's signature and representative menu item. You have to try this!! There's also a Signature Blanc, which has more of a white cake feel, packed with white chocolate mousse, tangy cassis, and nutty pistachio.

Mascaberry

Mascaberry dessert topped with blueberries

Mascaberry, ₩13,500. A dessert with a sweet vanilla base topped generously with tangy blueberries. It was one of the less sweet items I tried, but it was the kind of dessert my hand kept reaching for.

Vanilla Earl Grey milk tea

Notldun vanilla Earl Grey milk tea

Vanilla Earl Grey milk tea, ₩7,500. A very special milk tea brewed with vanilla and Earl Grey — I think this was an unforgettable milk tea. You can properly enjoy the clean yet nutty, rich flavor of the milk tea.

Cappuccino

Notldun cappuccino with thick milk foam

Cappuccino, ₩7,500. Full of thick milk foam with an espresso shot in it too, so you can also enjoy the coffee flavor.

Wrapping up: Notldun, a Seongsu dessert café

I was satisfied after my first visit and came back — and the second visit at this Seongsu dessert café, Notldun, was even better. A lot of people take dessert to go here, so even if the seats are full, it doesn't feel like too much of a letdown! I genuinely recommend it!
