The B1F of Sunbright Twin, directly connected to Nakano-sakaue Station, is called PAO Square.

It's a square where restaurants and specialty stores gather.

Look for the slightly unusual red umbrella object as a landmark.
There's space to sit at its base.

By the way, I ate an onigiri (rice ball) here.
It can also be used as a meeting place in Nakano-sakaue.
Also, I've uploaded a video of my visit on YouTube, so I think you'll get a sense of the atmosphere right away.
So, why not use it as a relaxing spot near Nakano-sakaue Station?
