If you think this is a boarding gate, it is not. It is the third/top floor of the Taipei Songshan Airport used for Observation Deck. Me and my son went there in the late afternoon last Sunday, without passports. I have been wanting to take him here for a while and finally it was my turn to babysit him and the time is perfect to watching airplanes landing and taking off! So we spend the second half of the afternoon and early evening in this airport right in the middle of the city, approachable via city metro. The place is safe (well, theoretically your chances of getting hit by a plane should go up quite a bit though), well maintained, clean, full of food choices, and heaps of fun for watching how this airport functions on the ground. As you can see, this place has become a hot spot for parents spending time with their kids. You can check this link for official information.

Conclusion: this is a great place for local parents who love airplanes or airports to spend time with their kids. But. this is also a nice hidden venue for travelers who are using this airport if you hope to spend some time having fun without worrying about not being able to catch your flights.
