During a trip to Kaohsiung I asked a friend for cafe recommendations. This was the first one he recommended, and it was definitely a great choice. The space is very large, feels modern and bright, with lots of natural light. There are plenty of seating options, and I especially liked the large worktables and the individual counter seats in the back (popular for working or studying).
The menu is quite cheap, and has both food and drink, so it's definitely suitable for a working brunch/lunch. I tried the bacon & peanut butter toast, which was quite good.
The WiFi was fast, there were plenty of power outlets. If I was living in Kaohsiung this would definitely be a regular spot!
