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.

A 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's first cafe in Korea, opened 3 May 2019.

A 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.
