Star Rocket Café is located on the 11F of the Syntrend department store. On a weekday it's very suitable for working, as it's usually quiet and plenty of seats. The large worktable in particular is comfortable and good for working. They offer basic food and drinks. The drawbacks are that the WiFi is a little slow and disconnects occasionally, and the opening hours are quite short. Extension cords are available if you ask the staff.
To reach the cafe, enter the main entrance, take a right and find the elevators. Take the elevator up to the 11th floor and follow signs for the Star Rocket Cafe.
The cafe inside the Xinyi Eslite department store opens early and closes late, great for those who need to get to work done during off-peak hours. However, the lack of WiFi and power outlets makes this a difficult work spot. Be sure to arrive fully charged and bring a mobile hotspot. At least the interior and views are nice and the seats are comfortable. Food and drinks are a little pricey. You'll need to use one of the street level entrances to access the cafe when the department store is closed.
A very unique cafe, and if you're into Taiwanese tea then this is probably one of the better cafes in Taipei. The cafe is located on the second floor of an old building. You'll likely miss the tiny entrance if you aren't paying attention. The cafe space feels large and spacious, filled with old furniture and large wooden beams in the ceiling. It definitely has a special vibe!
Just keep in mind, you'll probably want to make a reservation. There are only 3 small tables right by the entrance that are available without reservation (first come first serve), and most other tables are usually booked.
