Seoulsup dessert café with kids before night insect class: Notldun

In short

Notldun is a dessert café on Seoulsup 2-gil in Seongdong, Seoul, near Ttukseom Station and Seoulsup. Arriving early with a child before a Seoulsup night insect class, the writer walked into Notldun with no wait, ordered Forêt Noire, a salted caramel mille-feuille and a strawberry latte, and browsed the open kitchen and baked-sweets gift packages. Notldun is a good Seongsu dessert café to enjoy with kids before or after a Seoulsup outing.

Why we stopped at Notldun before the Seoulsup night insect class

On the day my child and I signed up for a night insect class at Seoulsup, we got to Seongsu early and stopped by the dessert café Notldun (노틀던). Since we were early, we even squeezed in a little date, haha. It's such a great dessert spot that I keep thinking about it, this Seongsu Notldun!

Desserts we picked from the Notldun display case

The showcase was packed with desserts and my child was thrilled. Look how excited my kid is at a Seongsu dessert hotspot! Both of us were feasting our eyes on the full showcase. Pretty from far away, pretty up close!! *_*

We talked about the cake we had last time, then started with the salted caramel mille-feuille that I'd wanted before but was sold out!

Notldun's open kitchen and Valrhona 40th anniversary dessert

Notldun has an open kitchen, so we could watch the desserts being made. The workspace is spotless too!!

How does Notldun's Forêt Noire taste?

Notldun's Forêt Noire (포레누아) is a cherry cake, a meeting of a tart and a mousse cake. Enjoying it properly at a Seongsu dessert café! *_*

My child loved it, saying the cherry was super sweet! It feels so upscale!! A chocolate tart shell, chocolate cake layer, then cherry jam and mousse cake! The combination is absolutely the best! *_*

Pretty and delicious too, what could be better!! The kind of taste that keeps your fork going!!

Notldun's salted caramel mille-feuille has all my favorite things in one! And it's filled with cream!! *_* Smooth, sweet cream inside chocolate and crispy mille-feuille pastry, what a combination~

Is Notldun a good dessert café for a Seoulsup outing with kids?

Great atmosphere and great taste, a Seongsu dessert hotspot! A lovely place to buy dessert gifts, and the packaging makes it even better!! *_*

Cozy interior of Notldun

Not only is it good for a Seongsu date, the tasty desserts make you even happier!! *_* Seoulsup is close by, so it's perfect to come for a Seoulsup date and enjoy Notldun too!!

In a Seongsu café with a lovely mood, I ate dessert in comfort and even finished a whole fun book, a relaxed stretch of time!!

Time spent reading a book at Notldun

If you're looking for a Seongsu dessert hotspot, I recommend Notldun! A day of tasty desserts at Notldun and a proper insect exploration too. Next time I visit Seoulsup, I'll come to Notldun for Seongsu desserts again! *_*
