The feeling is kinda similar to going to some high-tech building or space station. I dunno why. I can't explain. Haha.

I am not kidding when I say the stores are located at the core. 

The view of the core from the top of the elevator. 

The food court is located at the basement. But I was quite full that day so I did not buy anything from here. =P

Core Pacific City Living Mall is located at the Taipei City Hall area. You can see the map below to see the location of the mall.
