I’m Donut? Seongsu (Seoul, SOUTH KOREA) ★★★★☆

My favorite donut chain, I’m Donut?, has expanded heavily into Seoul last year, with three locations in the trendy neighborhoods of Seongsu, Hongdae, and Gangnam (inside Shinsegae).

Known for their melt-in-your-mouth “nama donuts” (raw/fresh donuts) made with chewy rice flour, their signature treats are famous for an incredibly fluffy texture. In Seoul, they’ve introduced Korea-exclusive flavors like bossam (pork belly) and seaweed glaze to tame the taste buds of Seoulites.

As a huge fan of I'm Donut?, I decided to swing by for a quick breakfast the moment I arrived in hipster Seongsu-dong. his is their flagship branch, and not surprisingly there were over 30 flavors to choose from — classic signatures, cream-filled varieties, savory options, and of course the Korea-exclusives.

Maple prosciutto (₩4,800) — While the Bossam collection looked like the perfect savory breakfast choice, I went with this one instead — two slices of prosciutto (premium Italian dry-cured ham) on top of a maple glaze. The salty notes played really well with the sweetness. Not bad at all.

Muscat grapes (₩5,200) — But this one was even better.

The natural sweetness of the Shine Muscat grapes really shone through beautifully against the custard cream and fluffy dough. I loved it.

Surprisingly, there wasn’t much of a line at the flagship store. In fact, another viral bakery called Haz Bakery just a few steps away had an even longer queue.
