The weather was so nice that I casually headed out for a picnic. More and more people are looking for Seoulsup cafés and Seongsu cafés these days, and I'm joining the trend. ![Overdose Donut & Coffee Seongsu, stopped by on the way to a Seoulsup picnic](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-01-rhpl2-1200.webp) I was looking for a snack that was simple but special to eat on a picnic, and that's how I ended up at Overdose Donut & Coffee Seongsu. ![Overdose Donut & Coffee Seongsu donuts chosen as a picnic snack](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-02-1ja30-900.webp) Once I got there, it felt like a donut-focused café even among Seongsu desserts, not just a Seongsu bakery but a stylish Seongsu dessert café. I thought takeout donuts would be great to eat on a Seoulsup date, so I visited, and in the end it was a pretty satisfying choice. ### Overdose Donut & Coffee Seongsu hours and parking Overdose Donut & Coffee Seongsu is open Tuesday to Sunday, 11:00–19:30, and closed every Monday (open as normal if it falls on a holiday such as a substitute holiday). For parking, I recommend using the public parking lots nearby. ## Where is Overdose Donut & Coffee Seongsu, and what does it look like outside? Overdose Donut & Coffee Seongsu is inside a side street close to Exit 7 of Ttukseom Station. I found it while searching for cafés near Ttukseom Station. It's easy to reach even among Seongsu cafés, and being inside an alley, the quiet atmosphere left an impression. ![Exterior of Overdose Donut & Coffee Seongsu in a side street near Ttukseom Station](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-03-1lrb9-900.webp) ![Black exterior wall and OVDZ sign at Overdose Donut & Coffee Seongsu](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-04-15ig5-m-900.webp) The black exterior wall with a neat OVDZ sign caught my eye. It has a strong Seongsu hotspot feel, but it doesn't stand out too much, and the restrained design actually felt more attractive. ![Understated entrance of Overdose Donut & Coffee Seongsu](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-05-1byxc-900.webp) The building has a 1.5-floor structure, and as you climb the stairs and see the special icon, you start to expect a good Seongsu dessert café. ![Stairs up to the 1.5 floor with the Overdose icon](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-06-1hl6t-900.webp) Not many Seongsu bakeries look this stylish from the outside, and Overdose has a clear brand concept. ## Inside Overdose Donut & Coffee Seongsu The interior carries on the black tone of the exterior, with orange as the accent color. Thanks to this combination, the atmosphere felt alive. ![Black-toned interior of Overdose Donut & Coffee Seongsu](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-07-19mf2-900.webp) ![Overdose shop interior with orange accent color](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-08-4tt0s-900.webp) This combination gives the impression of a space with Overdose's own firm concept, not just another Seongsu café. ![Seating with black tables and chairs at Overdose Seongsu](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-09-c42s3-900.webp) The tables and chairs are black accents, and the donut icons on the wall were cute but not overdone, which I liked. It was a space where the stylish interior typical of Seongsu-dong cafés really came through. ![Interior of Overdose Seongsu with a donut icon wall](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-10-etzkl-900.webp) The window side has full-length windows with lots of sunlight, so it also gave a Seoulsup café feel. ![Sunlit full-window seats at Overdose Seongsu](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-11-1eaxu-900.webp) It was a good enough place to sit down and relax over a cup of coffee. I came for Seongsu desserts, but the space itself was also quite satisfying. ## Overdose Donut & Coffee Seongsu menu and the 4-donut set The menu at Overdose Donut & Coffee Seongsu comes with pictures, so it was intuitive and easy to understand. ![Illustrated menu board at Overdose Donut & Coffee](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-12-rxwzb-900.webp) ![Menu board detail at Overdose Donut & Coffee Seongsu](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-13-114hy-900.webp) Personally I like a Seongsu bakery with an easy-to-read menu like this. I hear Overdose makes its dough and cream by hand every dawn, with a principle of same-day production and same-day disposal. That freshness is appealing. ![Overdose donut display, made fresh and sold the same day](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-14-728oz-900.webp) I looked ahead of time and chose the 4-donut set. ![Overdose 4-donut set ordered for takeout](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-15-5d71i-900.webp) The four items I ordered for takeout were: - Corn streusel donut - Jeju matcha & salt caramel donut - Rich Valrhona chocolate donut - Homemade Earl Grey donut ![4-donut set of corn, matcha, chocolate and Earl Grey donuts](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-16-6o5jd-900.webp) I was curious about the taste as a Seoul donut hotspot, and this lineup was quite good too. ## Overdose donut takeout: how did they taste? The takeout donuts from Overdose Donut & Coffee Seongsu were neatly wrapped individually so they didn't stick to each other. ![Individually wrapped Overdose takeout donuts](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-17-1mq14-900.webp) I felt this was a part they took real care with, even among Seongsu cafés. ### Corn streusel donut The corn streusel donut had a unique combination of nutty cream and torched corn. It's a menu item you rarely see at a Seongsu bakery, so it left an impression. ![Corn streusel donut topped with torched corn](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-18-5flhu-900.webp) The corn sits on top whole, so it looks fun, and the savory taste went well with the sweetness of the donut. ![Corn streusel donut with whole corn on top](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-19-1mzpv-900.webp) ### Homemade Earl Grey donut The homemade Earl Grey donut had a really strong Earl Grey aroma. ![Overdose homemade Earl Grey donut](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-20-tkhph-900.webp) It didn't feel like a merely sweet Seongsu dessert, but a flavor-focused one. ![Homemade Earl Grey donut with a strong aroma](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-21-1f0vn-900.webp) When you take a bite, the Earl Grey flavor fills your mouth, and it's sweet and classy enough that you keep eating. ![Homemade Earl Grey donut with a bite taken](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-22-gl7s6-900.webp) ### Rich Valrhona chocolate donut The Rich Valrhona chocolate donut wasn't overly sweet and felt upscale. ![Rich Valrhona chocolate donut with almonds](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-23-em5y9-900.webp) It wasn't just sweet because it's a chocolate donut; the refined sweetness and the crunch of almonds went together in a premium donut. I could understand to some extent why it's called a Seoul donut hotspot. ### Jeju matcha & salt caramel donut The Jeju matcha & salt caramel donut had a definite sweet-and-salty combination. With organic Jeju matcha cream and homemade salt caramel, it's a signature donut with great sweet-salty chemistry, and it's even cooler with Overdose's own icon drawn on it. ![Jeju matcha salt caramel donut with the Overdose icon](https://img.superchart.com/images/overdose-donut-seongsu-takeout-set/overdose-donut-seongsu-takeout-set-24-fcew3-900.webp) Matcha cream plus sweet-salty salt caramel: this was a combination that couldn't taste bad. It's a flavor kids would like too, so I thought it would be fine for a family outing in Seongsu. ## Is Overdose Donut & Coffee Seongsu worth recommending? Among Seongsu-dong bakeries, Overdose Donut & Coffee Seongsu is well balanced in taste, concept and space. Its location also connects easily to a Seoulsup date course, so it's very useful. Next time I'd like to relax in the shop with a coffee. If you're looking for a Seongsu hotspot that isn't overdone yet is highly satisfying, I can recommend it.
