Hayee Cake Shop

Hayee Cake Shop is a small take-out cake shop in a quiet residential area between Sadang and Isu stations, about a 10-minute walk from Sadang Station. There is no seating. It makes lettering cakes in fixed designs and flavors; you choose one, add a short message and pick it up at the shop, which also sells candles and other party items. Same-day orders are sometimes possible, the cakes on offer are posted on Instagram, and reservations go through Kakao Talk or by phone.
