Go through the side entrance, the front is take-out only (pricing is slightly more expensive for seating). When entering the cafe, pick a table on the first two floors (3rd floor is just an event space) then order at the counter.

Overall I'd say this cafe is great for having a nice lunch and doing some work or study. I would definitely recommend getting a seat on the second floor, which was very quiet, has plenty of natural light, and comfortable seats.

The menu has many drink options, including some nice Taiwanese tea. For food there are bagels, but the staff asked if I wanted to try the daily special instead, which was korean style chicken and rice. It was really good and filling!

Be sure to arrive early though. After around 1pm on a weekday it starts to fill up quickly. Also note that there is a 3 hour time-limit during weekends and holidays.
