A to B Seongsu
에이투비 성수
A cafe-bar on the second floor of 135 Achasan-ro: coffee and desserts by day, cocktails and highballs in the evening. DiningCode lists 12:00–23:00 daily with last order at 22:30, so it is closed in the morning and fits better into an evening plan. The signature item is "pigotchi", dried persimmon topped with cream cheese and pecans (₩10,000). It is about 170 m from Seongsu Station Exit 2.

Reservation
Polle lists phone booking while TripInfo says reservations are not taken, so the sources disagree. Do not count on booking by phone in Korean; plan on walking in. Reviews say weekend afternoons get busy.
Payment
TripInfo lists credit cards as accepted. Whether foreign-issued cards go through was not confirmed.
Hours
Daily 12:00–23:00 · Last order 22:30
Tips
- DiningCode gives 12:00–23:00 every day, while TripInfo has it open until midnight on Fridays and Saturdays, so the weekend closing time depends on the source. If you plan to stay late, check Naver Map or the venue's Instagram for the day before you go.
- About 170 m from Seongsu Station (Line 2) Exit 2, on the second floor. No parking. TripInfo lists it as pet-friendly.
Seongsu · Places
AayAan Seongsu
아이안 성수A dessert cafe on the third floor of 3 Wangsimni-ro 4ga-gil, centred on tarts and ice cream such as a fig tart and a honey-fig ice cream (₩13,000 each). It opens after midday and runs to around 23:00, so it does not work for a morning plan. Posted hours and closing days vary widely between sources — read the tip below before going.
Blue Bottle Coffee Seongsu
블루보틀 성수 카페Blue Bottle's first cafe in Korea, opened 3 May 2019. It is the red brick building outside Ttukseom Station Exit 1 — the ground floor holds the roastery that supplies Blue Bottle's Seoul cafes, and the seating is one level below. Multiple sources note the seat count is small. The official site lists 08:00–20:00 daily.
Cafe Dasique Seongsu
카페데이지크 성수A dessert cafe on the second floor of 6 Yeonmujang 5-gil. According to visitor reviews, the ground floor is a store of the cosmetics brand Dasique and the interior is pink-and-white marble. DiningCode lists 11:00–20:00 daily with last order at 19:00, so ordering stops an hour before closing. Individual cakes are listed at ₩14,000–₩16,000 and whole cakes at ₩55,000–₩59,000.
Cafe Onion Seongsu
어니언 성수The warehouse-conversion cafe that made Seongsu famous. Walk-in only — timing is everything. Signature: cream cheese garlic bread.
