Arriving sweaty after a bike ride, we ordered the mascaberry cake, a lemon madeleine and TWG French Earl Grey, and the cut side of the mascaberry sent blueberries pouring out like an active volcano. Notldun is the first dessert in a long while that genuinely impressed us, so it makes a perfect stop after a lap around Seoul Forest. ## Good to know - **Location**: 11 Seoulsup 2-gil, Seongdong-gu, Seoul, 2nd floor (backstreet behind Seoul Forest) - **Time limit**: 90 minutes for dine-in; takeout customers can walk straight in - **What we ordered**: Mascaberry cake, lemon madeleine, TWG French Earl Grey - **Mascaberry ingredients**: Mascarpone (France), blueberries (Korea), fresh cream (France) - **Gift options**: Financier selection, madeleine selection box *as written by the visitor on Sep 19, 2026* ![Table with dessert and tea at Notldun, Seongsu](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-01-1s02a-1200.webp) ## Notldun: a Seongsu dessert café upstairs in a Seoul Forest backstreet Notldun in Seongsu dessert spots. I've always loved the backstreet behind Seoul Forest. I passed by it so many times, and only today did I finally go in. Maybe it was because I was sweaty from cycling and needed sugar, but I felt pulled up the stairs to the second floor like a magnet defying gravity. The kitchen you see from the entrance. Pastry chefs in white gowns moving in perfect coordination. It's a scene straight out of a drama. The dessert cakes lined up in the display case are incredible. Calling them beautiful isn't enough. I was amazed at how they stood in a row like works of art. Whichever one you eat you feel fully satisfied, and whichever one you pick, you're bound to feel a twinge of regret over the ones you didn't. After much deliberation: mascaberry cake, lemon madeleine, and TWG French Earl Grey. There was exactly one reason I chose the mascaberry — I love mascarpone. Mascarpone (France), blueberries (Korea), fresh cream (France). The origins read like a friendly match between France and South Korea. After cutting it, the cross-section looks almost like an active volcano spewing blueberries. Insanely soft, tangy, and creamy. My eyes closed on their own, and my brow furrowed in genuine disbelief. Lemon madeleine. As a madeleine enthusiast, I've been working my way through all kinds of them. The balance of sweet madeleine coated in tart lemon is wonderful. TWG French Earl Grey. An Earl Grey with astringency that neutralizes the sweetness. That's a compliment. After all that sweetness, you need this kind of astringency to complete the experience. It's been a while since a dessert genuinely moved me. This is the one — the Seongsu dessert spot. I think this is the hottest alley in Seongsu. Tucked into the cute backstreets behind Seoul Forest, here's a Seongsu dessert spot worth introducing. It's moving. > Notldun, Seongsu ## How to find Notldun and how entry works ![Exterior of the 2nd-floor building housing Notldun in the backstreet behind Seoul Forest](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-02-2zvei-900.webp) Here it is. Second floor. Notre Don. Notldun. ![Notldun coffee, drinks, and dessert signage](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-03-qvgok-900.webp) Notldun, Seongsu. Coffee, drinks, dessert. Once you've made it this far, you're basically there. Ready to be moved?!! ![Sign at the entrance of Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-04-e86t9-900.webp) Even from a quick glance at the photos outside, I was already drawn in. 1.5 hours of use for dine-in; takeout guests can go in right away. And Compassion — a table of sharing that helps save children's lives. They're doing good work. ![Notice about store usage time and a sharing campaign at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-05-jg9xa-m-900.webp) ## Inside Notldun: the white-coated pastry kitchen and the cake showcase First time seeing something like this. Partly because I don't eat dessert that often, but it reminded me of scenes from a drama — pastry chefs in white gowns inside the kitchen. ![Pastry chefs in white gowns working in the Notldun kitchen](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-06-1npd7-900.webp) This is Notldun's mark. ![Notldun logo mark](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-07-6awwd-900.webp) ![Interior of the Notldun store](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-08-18tip-900.webp) ![Dessert showcase at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-09-hnbqv-900.webp) Dessert. ![Slice cakes displayed in the showcase](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-10-10b5t-900.webp) ![Close-up of the Notldun dessert display case](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-11-1m93d-900.webp) There are so many kinds of madeleines too. ![Various madeleine flavors displayed at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-12-60v7e-900.webp) The financier selection. If you buy a box separately, it seems like a great gift. It's classy enough as a thank-you gift that the recipient would probably smile. ![Financier selection gift box at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-13-1cj5y-900.webp) The drink prices are around this range. I went with the TWG French Earl Grey. ![Drink menu board at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-14-12ale-900.webp) A collaboration with Guanaja. ## Mascaberry cake, lemon madeleine and TWG French Earl Grey at Notldun Sat down at my table. Mascaberry cake, lemon madeleine, and TWG French Earl Grey. ![Mascaberry cake, lemon madeleine, and TWG French Earl Grey set on a table](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-15-tz4hp-900.webp) I picked a perfect combination of three without even planning it, and surprised myself. - Mascaberry cake - Lemon madeleine - TWG French Earl Grey ![Tableware setting at Notldun with an upright knife](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-16-z7nt7-900.webp) The tableware is incredibly nice too. I love that the knife stands upright. ![Close-up of the mascaberry cake](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-17-1nkyg-900.webp) Cut it open. Actually, 'cut' isn't quite right — more like it unfolded into a flower. The mascaberry became a flower. Total volcano, lava-like blueberries pouring out. What am I supposed to do with this softness?! What am I supposed to do with this tanginess?! You can just barely see my bike tied up outside. Slicing the madeleine. ## Notldun madeleine and financier selections to take home as gifts Browsing the display. The madeleine selection would make a great gift too. ![Dessert display at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-18-gjfy7-900.webp) ![Close-up of cakes on display at Notldun](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-19-1kobs-900.webp) ![Notldun desserts displayed like works of art](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-20-ms4td-900.webp) ![Lineup of desserts in the Notldun showcase](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-21-7jivu-900.webp) ![Side view of the Notldun dessert display](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-22-lkij8-900.webp) ![Notldun desserts arranged like museum artwork](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-23-ryfrj-900.webp) Photographed like this, it looks like artwork from a museum, and it puts me in a great mood. ![A dessert photo at Notldun with a greenish tone](https://img.superchart.com/images/notredon-seongsu-lemon-madeleine-twg/notredon-seongsu-lemon-madeleine-twg-24-uaqvw-900.webp) The last photo is a refreshing green. Let's cleanse our eyes. A Seongsu dessert spot, Notldun in Seongsu. The ultimate bite made by a dessert artisan. A place you absolutely must visit after a lap around Seoul Forest. You'll see the furrowed brow of truth. ## Where it is - Notldun (노틀던) - 11 Seoulsup2-gil, Seongdong-gu, Seoul, 1st floor (accessed via 2nd floor entrance), South Korea - 서울특별시 성동구 서울숲2길 11 1층 - 37.5473614, 127.0400154 - Google Maps: https://www.google.com/maps/search/%EB%85%B8%ED%8B%80%EB%8D%98/@37.5473614,127.0400154,17z --- Superchart · https://superchart.com/en/@rice-plate-seoul/notredon-seongsu-lemon-madeleine-twg/ · https://superchart.com/llms.txt
