Seongsu dessert cafe A to B sits on a quiet street near Seoul Forest, making it easy to spot thanks to its bold vintage-style signage. The entrance feels casual yet intentional, with a bar-like aesthetic that hints at the cafe’s late-night vibe. It’s the kind of place you can walk past once and immediately note as “interesting,” especially if you’re exploring the Seongsu area on foot.

Interior & Seating

Inside, A to B has a warm vintage interior with low lighting, wall decor, and cozy lounge-style seating. The main room has more tables toward the back, and there’s also a bar counter area that gives the space a slightly late-night cafe feel. It was fairly busy during my visit, so I couldn’t photograph the back section, but there were more seats available beyond what’s shown here — including the bar seating.

Seongsu Dessert Cafe — Banana Brûlée Coldmisu

At this Seongsu dessert cafe, the signature pick is the Banana Brûlée Coldmisu — a tiramisu-style dessert topped with caramelized banana slices. The combination sounds like it could never go wrong, and it genuinely doesn’t. It’s rich, creamy, sweet in a balanced way, and surprisingly easy to finish without feeling heavy. If you enjoy tiramisu or banana-based desserts, this is the one to order.

Menu Highlights

Hunter Latte is one of A to B’s signature drinks — essentially a flat white topped with ice cream, Valrhona chocolate, and cinnamon.
It sounds indulgent, but it’s surprisingly not heavy or cloying, and the balance makes it easy to finish. If you like ice cream lattes but don’t want something overly sweet, this one is absolutely worth trying.

Cheonsang Gaok, another Seongsu dessert spot, is only about a 6-minute walk from A to B — perfect if you’re exploring cafes in the neighborhood: https://0ddungs.kr/cheonsang-gaok-seongsu-cafe-greenhouse-christmas-desserts/
