Is Overdose Donut & Coffee Seongsu worth lining up for at opening?

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 😊

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😊

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 😊
