The story
Nestled in Seoul’s Jongno District, Cafe Onion has become an OG Instagrammable destination, thanks to its beautifully renovated hanok setting. According to creator Doobydobap, the interiors alone are worth the visit, offering a scenic blend of traditional Korean architecture and modern cafe culture.
On the food front, Doobydobap highlights two standout items. The butter sticky rice cake, she notes, is “surprisingly good,” while the Dubai Chewy Cookie also earns her approval.

AI summary of what 2 dish mentions say about the food
Cafe Onion’s Dubai chewy cookie is a standout, praised for its satisfying texture and bold sweetness. Reviewers describe the overall vibe as cozy and indulgent, perfect for a comforting treat.
“This is the trendiest Dubai chewy cookie, which took Korea by a craze. I am a certified hater, so this is my first try. Inside there's kadayif, which is fried thin Arabic-style noodles often used in desserts. It's like between a mochi and a marshmallow fluff. You get the crunchiness from the kadayif noodles, the creamy nut butter, and the chewy marshmallow fluff on the outside. But overall, it's really dry. The mouthfeel is interesting, but is it something to froth over? No. It's also incredibly difficult to eat. It looks like I ran out of doggy bags and had to pick up my dog's poop with my bare hands. 5 out of 10.”

Butter Sticky Rice Cake
This is the next viral thing. It has a pretty hard glazing and reminds me of a French-style canelé, double-baked so it gets that nice caramelization, but more of a melon shape. It's very dense, chewy, crunchy. There's a burnt caramel flavor coming through. It's surprisingly not too sweet, maybe because of the burnt caramelness with the bitter note and slight saltiness inside that works really well. Do be sure to try. I was ready to hate on Onion because it's just Instagrammable, but this is pretty good. A trend I can get behind. 9 out of 10.
