New Seongsu Yeonbang yogurt café: dine-in Marron Single, Lazy Yogurt
In short
Lazy Yogurt Seongsu is a Greek yogurt café that has moved to a larger space on the 1st floor of Building B at Seongsu Yeonbang in Seongdong, Seoul. The writer, who had always ordered takeout, finally sat down in the roomier café for a favourite, the Marron Single with plain yogurt (7,300 won), plus a cold brew (2,500 won). Lazy Yogurt's thick, non-sour yogurt and nutty toppings make it a good meal replacement or a snack for a Ttukseom Han River picnic.

Lazy Yogurt Seongsu, my absolute number-one Greek yogurt spot, has moved to Seongsu Yeonbang, so I went to check it out. I love Greek yogurt so much that I've tried pretty much every famous place around Seoul, and this is where I ended up after all that wandering. Whenever I had a reason to be in Seongsu, I'd often grab a tub to go as a meal replacement. The new space is much bigger and more comfortable, so now there's no need to take it away. You can just sit and enjoy it at your own pace.
Where is Lazy Yogurt Seongsu, and what are the hours?
Lazy Yogurt Seongsu is at 14 Seongsui-ro 14-gil, Seongdong-gu, Seoul, Building B, Unit 102, on the 1st floor of Building B at Seongsu Yeonbang. It's open daily from 10:00 to 20:00.

It's 632 m from Seongsu Station Exit 3, about a 5-minute walk. The new spot in Seongsu Yeonbang sits on a route lined with hot places, so it's easier to get to than before.


The vibe at the new Seongsu Yeonbang shop
Now on the 1st floor of the nicely landscaped Seongsu Yeonbang, Lazy Yogurt Seongsu has gotten a real atmosphere upgrade. There's even a lovely terrace now, which would be perfect for sitting outside this time of year.




The inside is clean and cozy overall, good for coming alone and spending some quiet time, and it works fine as a date spot too.

The mood was perfect for pausing in a busy day and enjoying a slow moment. It's more comfortable and cozy than before, and the pretty interior holds its own against any café.

I noticed a familiar signature on the wall across from the counter, and it was Stella from Hatuha's! I had just been to the 2AN pop-up that same day and saw this signature there too.
What the name Lazy Yogurt means, and the menu


The name Lazy Yogurt has a special meaning. They use only top-grade raw milk with no unnecessary additives, and the yogurt is cold-aged for 72 hours. Calling this slow but careful process "lazy" is pretty charming, isn't it? People who make Greek yogurt always seem to have their own philosophy.
The sweetness is kept low so the flavor of the ingredients comes through, which makes it easy to have as a breakfast replacement, a healthy brunch or a light dessert. Besides yogurt, Lazy Yogurt Seongsu also has acai bowls, fruit bowls, bagels and more.
What I ordered: Marron Single ₩7,300, cold brew ₩2,500

- Marron Single ₩7,300
- Cold brew ₩2,500
The old shop was cramped, so I always took my order to go. This time I settled into a comfortable table and ordered my favorite combination.

There was a handwritten card announcing the move and thanking visitors, which honestly touched me a little.

What is the Marron Single, and how does it taste?
My favorite, the Marron Single, is a signature bowl with a Greek yogurt base piled with banana, dried fig, almonds and sunflower seeds. The recommended flavors are soy milk and peanut butter, so it's the ultimate nutty treat! But I like it with the most basic plain yogurt, so I ordered plain instead of the recommended flavors.

One bite proves the 72-hour wait: the yogurt is thick and rich like cream cheese with the moisture pressed out, and it fills your whole mouth.


The soft sweetness of ripe banana and the chewy texture of dried fig strike a fantastic balance with it.




Crunchy almonds and sunflower seeds here and there add to the fun of chewing. Overall, the great texture and nutty flavor go perfectly with the smooth Greek yogurt that has no tanginess. I've tried many menu items at Lazy Yogurt, but no combination has won me over like Marron.

Does Lazy Yogurt's cold brew go well with the yogurt?
The cold brew I ordered alongside was only ₩2,500, yet it tasted clean and refreshing. After the thick, nutty Greek yogurt, a sip of cold brew tidies up your mouth and lets you enjoy the yogurt at its best.
I recommend Lazy Yogurt Seongsu to anyone looking for a good spot near Ttukseom Han River, or a snack for a cherry blossom picnic.
