Seongsu Yeonbang café: four double-flavor Greek yogurts at Lazy Yogurt
In short
Lazy Yogurt Seongsu is a Greek yogurt dessert café on the first floor of Seongsu Yeonbang (Building B) in Seongdong, Seoul. Stopping in with her sister during a Seongsu pop-up tour, the writer ordered two double-flavor cups — matcha choco, pistachio, cinnamon caramel cookie and black milk tea — and chose four free jams from the Fontana collab: blueberry, apple, fig and pumpkin. Lazy Yogurt Seongsu is a light stop for days when sweet desserts feel like too much, and an easy stop on a Seongsu date course.

Hey everyone~ Today I went to Seongsu with my sister to check out some pop-ups, and wow, Seongsu was PACKED haha. My blood sugar was crashing so I figured I needed dessert, and right in front of my eyes was a Greek yogurt shop! I already love Greek yogurt, so of course I had to go in!! Here's my review 🤗

Where is Lazy Yogurt Seongsu, and what are its hours?
Lazy Yogurt Seongsu is located at 서울 성동구 성수이로14길 14 B동 102호, on the 1st floor of the Seongsu Yeonbang building. It's open daily from 10:00 to 20:00.
Seongsu Yeonbang itself is a cute building with lots to see, so you could easily spend a whole day there!


This is Lazy Yogurt — doesn't it have such a forest vibe,,🌱🍃 With the cooler weather these days, eating on the terrace would feel amazing! (Of course all the seats were taken, as usual)


Fontana jam collab: a free jam with every Greek yogurt order
When I visited, Lazy Yogurt Seongsu was running a collab with Fontana jam. Order a Greek yogurt and you get to pick a free jam.
I'd visited Lazy Yogurt a few months ago too, and this time they were collaborating with Fontana jam! I'd heard of Fontana pasta before, but I didn't know they made jam too! There were so many flavors I was already stressing over what to pick

Isn't this such a generous event~! The other jams felt kind of familiar, but I was really curious about the pumpkin walnut jam!!

Ordering at the kiosk, with menus in several languages
Ordering at Lazy Yogurt Seongsu is done by kiosk~ It looks like a lot of foreign visitors come here too, since the menu is available in different languages.

Here's what the menu looks like


They scoop the Greek yogurt right in front of you — it looks super clean and I could watch the whole process, which made me trust it more! Kind of like an ice cream shop, and I loved that haha


Two double cups, four flavors: matcha choco, pistachio, cinnamon caramel cookie, black milk tea
Ta-da~ Here's what I ordered! I got two double-flavor cups, so I got to try four flavors total. Let me show you each one in detail below

I went with matcha choco and pistachio, and cinnamon caramel cookie and black milk tea.
- Matcha choco — the bitterness of matcha meeting the sweetness of chocolate, a combo I kept coming back to
- Pistachio — nuttiness spreads the moment you take a bite, a must for pistachio lovers
- Cinnamon caramel cookie — cinnamon aroma and caramel sweetness blend for a full-on dessert feel
- Black milk tea — a charming balance of rich black tea aroma and smooth milk

The four Fontana jams we picked: blueberry, apple, fig, pumpkin
For jams I chose blueberry, apple, fig, and pumpkin.
- Blueberry — a rich, sweet-and-tangy blueberry flavor that paired perfectly with the yogurt
- Apple — clean, light sweetness that was easy to enjoy without feeling heavy
- Fig — a subtle sweetness that builds as you chew, giving it a luxurious feel
- Pumpkin — the soft, sweet flavor unique to sweet pumpkin, giving off an autumn dessert vibe
Is Lazy Yogurt Seongsu worth a stop on a Seongsu café tour or date?
If you're looking for a dessert in Seongsu that's healthy but still delicious, I recommend Lazy Yogurt Seongsu! You can enjoy thick, creamy Greek yogurt with all sorts of topping combos like matcha choco, pistachio, cinnamon caramel cookie, and black milk tea, and with this Fontana jam collab on top, it was fun picking exactly what suited my taste.
It's light enough to enjoy even on days when a super sweet dessert feels like too much, making it a great spot for a Seongsu date or a café tour course.
