at the Sony Center

The heart of the Sony Center, is a central plaza dramatically canopied by a tentlike glass roof
with supporting beams emanating like spokes of a bicycle.
The plaza and its many cafes are great for hanging out and people-watching.(Source Lonely Planet).

It is also a good place for spending money at the Sony Store as this happy customer (;-)).
