The writer came with her older sister and shared a fig Greek yogurt croffle, a tiramisu affogato, the signature Nutmo Sphere ice and an iced americano at a wood-toned table.

It's tucked in an alley off the busy main street of Seongsu-dong, so it actually feels more relaxed here. As soon as I got to the café, the exterior already looked kind of hip — classic hip Seongsu 🧡 You don't walk straight into the 1st floor — there's a staircase off to the side, and you take that up to the 2nd floor ^^! The stairs are a bit steep but let's go on up ^^!! 💛 ![Staircase beside the building leading up to Biat Seongsu's 2nd floor](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-02-cterl-900.webp) ![View near the 2nd floor entrance of Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-03-2x1rz-900.webp) ![Dessert showcase at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-04-1sx68-900.webp) ![Popular desserts displayed in the showcase at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-05-xmmed-900.webp) ## What we ordered at Biat Seongsu True to its reputation as one of the best cafés in Seongsu for cake, the showcase had all its popular desserts laid out beautifully! Both things I wanted were right there ^^! It's fig season these days!! (Even though neither my sister nor I are big fig fans...!) But I couldn't resist the look of the fig Greek yogurt croffle!! 😆 - Fig Greek yogurt croffle - Tiramisu affogato - A cold iced americano (is it even fall? I was sweating so much!!!!) - Nutmo Sphere ice So that's what we ordered!! 💛 ![Table ordering guide and menu at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-06-ezrti-900.webp) ![Coffee beans on display at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-07-1dnmu-900.webp) You can order right at the table! They also had the coffee beans they use on display so you could take in the aroma!!

Both sides are that good. Biat Seongsu really is huge and roomy inside! It's all done in warm wood tones with tasteful little objects placed here and there, so everywhere was a great photo spot!! Honestly there wasn't a single unpretty corner!! 😆 And each seating area has its own mood, so it was fun to pick a spot that matched what we felt like ㅋㅋㅋ This is the outdoor terrace seat — looks like there's only the one, and the door was firmly shut so we didn't bother opening it, but it does have a nice vibe ^^ though what mood were the two of us even looking for here ㅋㅋㅋ our indoor seat was plenty pretty too!! 🧡 ![Desserts and drinks on a wood-toned table at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-16-gi8g1-1200.webp) Wow!!! The visuals are amazing!! This one passes the test as a Seongsu Station café dessert spot!!!! So so pretty 💛 A million photos taken! The wood-toned tables go so well with the desserts! If you're looking for a Seongsu Station café dessert with great visuals, this place is perfect for you! ![Greek yogurt croffle topped with fig](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-17-1fx5z-900.webp) ![Cross-section of the fig Greek yogurt croffle](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-18-1vzfn-900.webp) ## What the fig Greek yogurt croffle tastes like ❣️ Fig Greek yogurt croffle. From the moment it arrived, this dessert was already pure photo-mood material!! The croffle (croissant waffle) was seriously crisp, layered with thick, soft Greek yogurt in between, so cutting into it with the ripe fig, the fig's gentle sweetness and the yogurt's tangy freshness came together perfectly, and with the croffle being insanely crunchy on top of that, this combo was so so good!! Neither my sister nor I even really like figs and we finished the whole thing ㅋㅋㅋ who said we don't like figs!! ![Iced americano served alongside the croffle](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-19-e8axq-900.webp) ![Tiramisu affogato at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-20-1xr6e-805.webp) ## Is the tiramisu affogato worth ordering? ❣️ Tiramisu affogato. A harmony of mascarpone cream and soft-serve ice cream between layers of genoise cake sheet! I scooped up the soft serve first — it's so soft and delicious! But then I scooped up the mascarpone cream together with the soft cake layer in one bite!! This was also incredibly good 🧡 ![A spoonful of tiramisu affogato with soft serve on top](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-21-g47i4-900.webp) ## The signature Nutmo Sphere ice with peanut butter cream ❣️ Nutmo Sphere ice. When I first saw this on the menu I thought it was a dessert! The name is so unique! It's Biat Seongsu's signature menu item, made with a cream of peanut butter mixed with unrefined sugar plus caramel milk!! Whenever I go to a café I always order the signature item. One sip and peanut butter aroma bursts through along with espresso and sweet cream together — so smooth and delicious! There are bits of sugar you bite into here and there too, which has its own charm 💛 Order this one, no question!! hehe ![The signature Nutmo Sphere ice drink](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-22-yqhtf-900.webp) ![Nutmo Sphere ice served with desserts on the table](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-23-7unz7-900.webp) Living up to its reputation as a great café for Seongsu Station dessert, everything was fantastic in both look and taste!! Next time I'll bring my mom too ^^ It's not just a coffee spot — there are so many delicious desserts that ordering a bunch to share was so much fun! It's. So. Good!! 🧡🧡🧡🧡 ![Full spread of desserts and drinks on the table at Biat Seongsu](https://img.superchart.com/images/biat-seongsu-nutmosphere-tiramisu-affogato/biat-seongsu-nutmosphere-tiramisu-affogato-24-b1fn8-900.webp) Beyond the dessert and coffee, Biat Seongsu's space itself is genuinely huge and spacious, so it's plenty pretty to photograph, and it has such a relaxed, comfortable atmosphere to enjoy in 👍 It's also a great date spot in Seongsu, so if you're visiting Seongsu-dong with family, a partner, or friends, I highly, highly recommend stopping by 💛 ## Where it is - Biat Seongsu (비아트 성수) - 24-45 Achasan-ro 5-gil, Seongdong-gu, Seoul, South Korea, 2nd floor - 서울특별시 성동구 아차산로5길 24-45 2층 - 37.5471439, 127.0542613 - Google Maps: https://www.google.com/maps/search/%EB%B9%84%EC%95%84%ED%8A%B8%20%EC%84%B1%EC%88%98/@37.5471439,127.0542613,17z --- Superchart · https://superchart.com/en/@order-pad-seoul/biat-seongsu-nutmosphere-tiramisu-affogato/ · https://superchart.com/llms.txt
