So I was sad because I bought a ticket to go on the rooftop, but it was raining, so I couldn't. But…read morethey refunded me automatically, so that was good. So instead I meandered between floors looking at all the art waiting for the rain to dissipate a bit. Some was cool, some I didn't get, to each their own.
It's a gorgeous building and worth a visit if you have the time. I'll have to come back for the rooftop next time!
