A 24-hour café by Sinnonhyeon Station
Today at Selecto Coffee by Sinnonhyeon Station, I enjoyed a smoked salmon sandwich and an Americano ☕️☕️☕️

Today I’m introducing Selecto Coffee, a 24-hour café near Sinnonhyeon Station! It is genuinely unusual to find a café open around the clock, and it also sells a range of sandwiches and desserts, so you can take care of a meal while getting all sorts of work done. On the right, there are even seats where you can relax outdoors in the breeze, so once the weather cools down, it would be nice to grab a spot there.

Once inside, it feels wonderfully spacious! Staff are on site only from 8 AM to 10 PM on weekdays and from 10 AM to 9 PM on weekends; during the relatively quieter late-night and early-morning hours, it operates unattended. The 24 Auto Brew area in front appears to switch on during those unmanned hours, and it seems you can both order and collect your drinks there.

How to order sandwiches and drinks
When I visited around lunchtime in the middle of the day, they were selling sandwiches for a healthy meal! There were varieties not listed on Naver Place, so have a look at the photo first. You can add dressing too, for even more flavor options haha.

Order whichever way feels easiest for you~ You can use the kiosk, or go to the counter if you have questions. At the self-service bar right beside it, you can pick up filtered water, extra cups, napkins, and wet wipes. It might be nice to take your time deciding while looking through the kiosk’s drink photos!

Just pick the sandwich you like and take it straight away hahaha 🥪🥪🥪🥪 Every one was generously packed with thick slices of salmon, plus a pretty substantial amount of what seemed to be ranch sauce spread between the layers!

First off, the coffee came in a fairly large cup, nice and cold with plenty of ice, while the sandwich was cut neatly in half for easy eating. You can eat one half first and save the rest for a little later~ Since you can help yourself to wet wipes and napkins, it was easier to keep clean while eating too haha.

I think there was one staff member there when I visited! It looked like it could have been hectic, but they were very kind haha 😃😃😃

A great space for café work and snacks
They were selling not only sandwiches but also desserts such as slices of cake. No need to go around looking for a restaurant and a café—you can take care of everything in one place! There is Wi-Fi and there are outlets too, so it looks really good for meetings or studying and working at a café.

On a clear, sunny day, there is refreshing watermelon juice to enjoy as much as you like, along with cup bingsu (a single-serving shaved-ice dessert) for a more compact but delicious treat~.~ 🍧🍧🍧

They also sell simple packaged snacks, so if you want a quick bite, I recommend the bagged snacks above as well.


The sandwich was generously filled with thick salmon and vegetables such as lettuce, while the decaf coffee tasted clean, without that characteristically unpleasant bitterness. The space is wide and the atmosphere is relaxed, so I recommend this place to lots of people.
