# Namhansanseong café for solo laptop work and Bora Bora Lemonade: Sum - By Hyerin Jo (https://superchart.com/en/@anyang-glass-window/) - Written Sep 15, 2026 - Local places › Cafés › Gwangju, Gyeonggi - Sponsored: This post was written after a sponsored visit to the store. - English edition: https://superchart.com/en/@anyang-glass-window/soom-cafe-namhansanseong-weekday-solo-work/ - Also in: [한국어](https://superchart.com/ko/@anyang-glass-window/soom-cafe-namhansanseong-weekday-solo-work/index.md) ## In short Sum is a large bakery café set back on a mountain road in Namhansanseong-myeon, Gwangju, Gyeonggi. On a quiet weekday visit alone, the order was a Bora Bora Lemonade to sip while working, with mammoth bread and a yakgwa (honey cookie) butter bar packed to go, and the walk around covered the main building's floor-to-ceiling window seats, the annex second floor across the sky bridge, the music room and the rooftop. Sum is an easy stop to fold into a Namhansanseong drive. ## Good to know - **Address**: 108-11 Ojeon-gil, Namhansanseong-myeon, Gwangju-si, Gyeonggi-do - **Hours**: Weekdays 10:00-20:30 / Weekends 10:00-21:30 (adjusted by season) - **Last order**: Weekdays 20:00 / Weekends 21:00 - **Parking**: Spaces in front of the café, plus extra parking below - **Amenities**: High chairs available, self-service bar - **Ordered**: Bora Bora Lemonade, mammoth bread, yakgwa butter bar *as written by the visitor on Sep 15, 2026* I'm always hunting for cafés to work from, so I combined that with a Namhansanseong drive and stopped by Sum 〰️ ## How do you get to Sum near Namhansanseong? Sum is a bakery café at 108-11 Ojeon-gil, Namhansanseong-myeon, Gwangju-si, Gyeonggi-do, near Ojeon-ri by Namhansanseong. There are so many cafés around Namhansanseong that I agonized over which one to pick before settling on Sum. ![View of Sum tucked into the mountain road at Ojeon-ri, Namhansanseong](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-01-17s3m-900.webp) It really felt like heading deeper into the mountains, so the drive there already felt like a trip. Driving around Namhansanseong always puts me in a good mood 🍃 Even with the navigation on, the road just kept winding through the mountains and I started wondering if there was really a café out here — haha, kind of scary. The road is narrow so it might be a bit tricky for new drivers. ## Sum's opening hours and reservations - Weekdays 10:00 - 20:30 / Weekends 10:00 - 21:30 - Last order: weekdays 20:00, weekends 21:00 - 🍃 Hours shift seasonally. - 🚙 Parking available 👶🏻 Baby chairs available - Reservations possible ## Is there enough parking at Sum? There's parking right in front of Sum, and there's another parking area just below it too! ![Parking space in front of Sum](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-02-clxjg-900.webp) I went on a weekday so it was pretty empty, but apparently on weekends it fills up completely and there's even a wait. ## What I ordered at Sum: Bora Bora Lemonade, mammoth bread and yakgwa butter bar Walking in, the bakery case was right there on display! Bread smell wafting through the air 🥖🍰 ![Bakery display case inside Sum](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-03-78mzc-900.webp) ![Assorted breads on display at Sum](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-04-19eus-900.webp) ![Bread trays at Sum's bakery corner](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-05-lovmn-900.webp) ![Sum's Bora Bora Lemonade with bakery items](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-06-vvhdp-1200.webp) I ordered the bestseller Bora Bora Lemonade along with a mammoth bread and a yakgwa (honey cookie) butter bar. I love the color purple, so ....~....💜 I packed the breads to go and just drank the lemonade while I worked. Gorgeous color and it tasted great too! ![Packed mammoth bread and yakgwa butter bar](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-07-11llz-900.webp) *The packed-up photo* The packed-up photo ## Inside and outside Sum: the mood of the café The angular exterior has a ribbon on the door that's just so cute. A little red ribbon accent 🎁 ![Sum's entrance door decorated with a red ribbon](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-08-1lndo-900.webp) The moment I opened the door, the faint smell of freshly baked bread drifted out! Being a bakery café, the interior felt cozy, and with such big windows the green scenery poured in — so easy on the eyes 🍀 ![Sum's interior with green scenery through large windows](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-09-wu8qr-900.webp) ![Window seats and interior decor at Sum](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-10-1vgx6-900.webp) ![Sum's calm interior seating area](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-11-iwzxv-900.webp) The space itself felt calm and warm.

Getting away from the city into a quiet space like this felt like real healing 🍃 ![High-ceilinged second floor seating at Sum's main building](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-15-rszbz-900.webp) There are second-floor seats too, with high ceilings. So refreshing. Cross the sky bridge and you reach the annex! ![Sky bridge connecting the main building and annex](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-16-5ntc8-900.webp) ![View of Sum's annex across the sky bridge](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-17-1d81a-900.webp) The Jajak Stay space on the annex's second floor, across the way ![Jajak Stay space on the annex's second floor](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-18-11bv6-900.webp) *The Jajak Stay space on the annex's second floor, across the way* ![Quiet second floor seating in the annex](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-19-i0302-900.webp) ![Window seat and drink on the annex's second floor](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-20-x8bkb-900.webp) There was no one else in this space, so I stayed a while and had my drink. ![Bora Bora Lemonade enjoyed on the annex's second floor](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-21-gqvjl-900.webp) ![Stairs leading down to the annex's first floor](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-22-1qw6o-900.webp) ## Annex music room, terrace and rooftop at Sum Head down the stairs and you reach the annex's first floor, where there's a projector setup and a music listening room. Seems like a nice spot to sit quietly and enjoy some music. ![Music listening room with projector on the annex's first floor](https://img.superchart.com/images/soom-cafe-namhansanseong-weekday-solo-work/soom-cafe-namhansanseong-weekday-solo-work-23-tr22j-900.webp) There's also plenty of outdoor terrace seating.

I'd definitely recommend stopping by Sum along the way 〰️ ## Where it is - Sum (남한산성 카페 숨) - 108-11 Ojeon-gil, Namhansanseong-myeon, Gwangju-si, Gyeonggi-do, South Korea - 경기도 광주시 남한산성면 오전길 108-11 - 37.4490874, 127.2258767 - Google Maps: https://www.google.com/maps/search/%EB%82%A8%ED%95%9C%EC%82%B0%EC%84%B1%20%EC%B9%B4%ED%8E%98%20%EC%88%A8/@37.4490874,127.2258767,17z --- Superchart · https://superchart.com/en/@anyang-glass-window/soom-cafe-namhansanseong-weekday-solo-work/ · https://superchart.com/llms.txt
