Seongsu lunch-break coffee shop, Pistachio Festival for four: Notldun

In short

Notldun is a dessert café on Seoulsup 2-gil in Seongsu, Seoul, an 8-minute walk between Ttukseom Station and Seoul Forest Station. On a workday lunch break, four coworkers walked over from the office and ordered two Americanos (₩12,000), a decaf caffe latte (₩7,000), a caffe latte (₩6,500) and the ₩15,000 Pistachio Festival, cut into four. The plan was coffee to go, but the dessert at Notldun was good enough to sit down for, and the hour ended with a walk through Seoul Forest.

Notldun's signature Pistachio Festival dessert

Working in Seongsu, one of our small joys these days is walking around during lunch and popping into cafés haha. Even going in totally at random usually works out! Today we grabbed lunch, headed out for a walk, and stopped at a café that turned out to be a serious dessert spot — got our sugar fix and then headed to Seoul Forest haha.

Where is Notldun, and what are its hours?

Notldun, a café in Seongsu, sits between Ttukseom Station and Seoul Forest Station — about an 8-minute walk. Great to stop by on a walk!

It stays open 30 minutes later on weekends, until 10:30pm — pretty late for a Seongsu café.

We had lunch and were walking over together haha, only 5 minutes from work!

Notldun from the street: a 2nd-floor café with full-height windows

Exterior of the 2nd-floor building where Notldun is located

There's a pretty café building, and it's on the 2nd floor! The floor-to-ceiling windows let you see right inside, giving it a really open feel.

Inside Notldun: seating and the dessert showcase

A clean white interior. It's not huge, but there was plenty of seating. Even without a lot of seats, it seems like a spot where people also come just to buy dessert as gifts. Being on the 2nd floor, the view is nice too.

Display shelf with madeleines

The cakes and madeleines were displayed neatly, all glossy and looking genuinely delicious! We came for coffee, but I already knew we'd have to order dessert.

Gift financier and madeleine selection set

There's also a financier and madeleine selection that's perfect for gifting. Nice that you can mix and match flavors.

I heard this place was featured on Cheonhajebbang (a baking competition show) episode 1. We spent a while browsing the madeleines and cakes deciding what dessert to get haha.

Our order: four drinks and the ₩15,000 Pistachio Festival

  • Pistachio Festival — ₩15,000
  • Americano x2 — ₩12,000
  • Decaf caffe latte — ₩7,000
  • Caffe latte — ₩6,500

We ordered four drinks plus the Pistachio Festival.

Pistachio Festival plated on the table

The Pistachio Festival! It had this slightly jiggly texture, almost like yanggaeng (sweet jelly) but also soft and fluffy. It's made with pistachio mousse, praline cream, and sponge.

Dessert and 4 drinks laid out on the table

And each of us got our own drink~ Since we've been eating a lot of heavy dessert and food lately, we mostly kept it to Americanos and lattes today haha. And happily shared one dessert between us~

Caffe latte dusted with cinnamon

The latte had a light dusting of cinnamon on top~

Looking closer, there was even gold dust sprinkled on it haha. We debated who should get it, and the person sitting across from me won the draw!! haha

Pistachio Festival split into four portions to share

How the Pistachio Festival tasted, split four ways

We happily cut it into four and each had a piece — it was seriously, seriously good!! You could really taste the pistachio flavor and aroma, and it wasn't an artificial sweetness — soft and melting in your mouth. We'd originally planned to just grab our coffees and go, but the dessert was so good we ended up sitting down and finishing our coffee too before leaving~ We came for coffee and fell for the dessert! A dessert spot good enough to give as a gift, no question.

Walking path through Seoul Forest after the café

After that sweet sugar refill, we walked over to Seoul Forest. Can't believe a place like this exists in Seoul. Walking around, it just made us happy. Thanks to a sweet, delicious dessert, we got a proper recharge on our lunch break before heading back to work haha. If you're looking for a great dessert spot near Seoul Forest, definitely check out Notldun!
