Blue Bottle Seongsu Cafe

Coffee is good, staff are friendly.

The space is spacious with both indoor and outdoor seating available. The staff are very kind; they even ask you to check the cups before finalizing the purchase. A unique feature is that you need the four-digit code from your receipt to enter the restroom, which is reserved for paying customers only. There is also a Lush nearby to browse, which is a great setup!

the coffee is so delicious.
