Overdose Donut & Coffee Seongsu is a donut café in Seongsu near Ttukseom Station, and if you go right at opening, you can pick the donuts you want without worrying about them selling out. I heard there was a great donut place in Seongsu, so I got up early and did the opening-time run to choose what I wanted before it was gone, haha.
Going right at opening meant I could browse at a relaxed pace, and that made it easy to pick the donuts I'd been wanting to try!

How to get there from Ttukseom Station, and the café's atmosphere
Overdose Donut & Coffee Seongsu is about a 5-minute walk from Ttukseom Station Exit 7, I'd say? It's very close to the station, so it's easy to find, even if it's your first time in the area 😊
Inside, the decor is clean and uncluttered, so the mood is comfortable. It's mostly brown with black accents, which gave it a stylish feel too. There are lots of tables for two, which is great for a small, low-key visit. The spacing between tables is comfortable, so it didn't feel cramped, and it seemed fine to come alone, a nice place to drop in casually 😊



Overdose Donut & Coffee menu and box discounts
There were 10 kinds of donuts in total, and you get ₩1,000 off a 4-donut box or ₩2,000 off a 6-donut box. It's fun to pick whichever you like, and with the discount, a box seems like the way to go!😊

There's also a Naver receipt review event running, so be sure to join in if you visit! It's simple to take part in, a nice little perk😊



Every single donut looked delicious, so my eyes were happy first. The cups were so pretty that I wanted to buy a coffee too, but I'd already had one before coming, so sadly I skipped it this time. Next time I'd like to enjoy coffee here as well😊

I bought a 4-donut box and got the ₩1,000 discount, then ended up adding one more, so 5 donuts in total! I headed home happily, haha😊




Which donuts to pick on your first visit
At Overdose Donut & Coffee Seongsu, I picked 5 donuts, mostly the ones marked as signature ("대표"). When I go somewhere for the first time, I always go for the menu items marked as signature, haha.
- Crème brûlée donut
- Jeju matcha & salt caramel donut
- Milk cream donut
- Injeolmi (roasted soybean powder rice cake) walnut donut
- Rich Valrhona chocolate donut
That's the mix I picked to suit my taste😊



What the Jeju matcha & salt caramel donut tastes like
The Jeju matcha & salt caramel donut pairs a rich matcha flavor with sweet salt caramel really well. I tried the matcha one first as soon as I got home. It went perfectly with tea, and the dough was soft yet chewy, which made it taste even better 😊




The milk cream donut and how my family reacted
The milk cream donut has cream that isn't greasy, just soft and mild, so it's easy to eat. In the evening I tried other flavors with my family, and my child raved about how good they were, haha. Personally, I thought the milk cream donut was really good. It goes so well with the dough that one disappeared in no time 😊
Would I go back to Overdose Donut & Coffee Seongsu?
Overdose Donut & Coffee Seongsu was a satisfying visit, with plenty of donut varieties and every one of them delicious. If you're looking for sweet desserts in Seongsu, I recommend stopping by at least once! Next time I'd like to try other flavors and have coffee too😊
