I walked through here this afternoon. Materials are terrific, although the big blocks & disks of white marble will no doubt get covered in grease stains as folks start using the plaza for lunch.
I tried to walk towards the south side of the plaza, near the entry to the US Customs Courthouse (aka the James L. Watson Court of International Trade Building), but was shooed away by the security dude. He said the public isn't allowed along that section of the plaza, between the building and the southernmost planting bed.
