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.

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.

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.

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.

The corn sits on top whole, so it looks fun, and the savory taste went well with the sweetness of the donut.

Homemade Earl Grey donut

The homemade Earl Grey donut had a really strong Earl Grey aroma.

It didn't feel like a merely sweet Seongsu dessert, but a flavor-focused one.

Rich Valrhona chocolate donut

The Rich Valrhona chocolate donut wasn't overly sweet and felt upscale.

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.

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.
