There are many great cafes around Zhongshan MRT, but most of them get very busy, even on weekdays. Recently I discovered Cafe a la mode, which was a quiet and less busy place to spend the afternoon working from. The interior feels bright and modern, and there are plenty of seats to choose from, including one large work table suitable for larger groups. There's decent WiFi, some power outlets, and comfortable chairs. The food menu is quite large, so it's probably a good place to have lunch or dinner as well, while getting some work done!
A simple cafe near Taipei Arena. The interior and furniture is fairly ordinary, but there are some nice personal touches, like paintings, magazines, and a fish tank. It's clean and the staff was friendly. Decent WiFi, but lacking power outlets. I saw one table near the back wall that has access to power. Nice drinks selection and the food options seem pretty good as well, so it might be a good cafe to have lunch at.
A great place for both indoor and outdoor working. The cafe is a popular spot for studying and working, but it is large so you can still find a seat most of the time. Fast WiFi, but power outlets are a bit difficult to find. I would say the biggest downside is that they close quite early.
I spent a day exploring Kita-Senju and this was my first stop. A large cafe not too far from the station. Very friendly staff. Unfortunately the menu doesn't have any tea. The walnut banana bread was very good. Excellent WiFi, but I didn't really see any power outlets (at least not at the large tables).
A cafe with delicious pastries and comfy counter seats. The WiFi was a bit slow, but still usable. I was able to take a call as well without much issues.
The cafe is very spacious but lacks seats for people who are alone. I felt bad for occupying the whole table for four seats. Anyhow, despite the google maps reviews saying that the WiFi is bad, I didn't have much problem at all. I ran a few speedtests and the fastest it recorded was 180 Mbps. However, there were some tests that scored around 30 Mbps, so I have to say it wasn't consistent. The music is really quiet. There are a few outdoor seatings for the smokers as well. Power outlets, you gotta find a good seat that's close to it.
A nice cafe near Seolleung station. The interior is quite spacious with plenty of natural light. Very fast WiFi and lots of power outlets. Usually not too busy, although it fills up a bit around lunch time. The only downside is that the nearest restroom is in the office building two doors down, which is a little inconvenient.
This library has plenty of seats and outlets to choose from. There are quite a few people working with their laptops open so seems like a normal thing to do. Wifi is not the fastest but stable. One thing that was annoying is that they probably block ports other than 80 or 443, so you can't SSH, connect to Postgresql DB, connecting to VPN, etc. For taking calls, if you go towards the kids area, you might feel more comfortable talking since there are kids who are also loud. However, there are signs that says no loud talking on the phone so not the best place when you have a day full of meetings. The out door benches are also available and the wifi speed doesn't drop too much even if you're seated outside. There's a supermarket right next to it so you can go grab some drinks if you need any. Edit - I could bypass the restriction by using Obfuscated Servers with Open VPN (TCP) protocol on NordVPN.
A very cozy and trendy cafe near Chiang Kai-Shek memorial hall. They open early (7:30) so it's a great spot to get an early start to your day. There's an extensive selection of drinks and desserts. If you're a group then you'll want to arrive early to get the large worktable. For solo-working I like the counter-style seats along the wall, although the table space might be a little small if you have a larger laptop. There's power but you may need to unplug a lamp. The cafe usually gets quite busy, and the staff may impose a 3 hour time limit.
