Downtown

 I had to go downtown to the financial center to get a form notarized the other day.  This involved leaving ID at the desk, getting a visitor pass, scanning in through gates which then assigned me to a particular elevator, and then checking in at the reception on the 25th floor -- a very controlled environment!

I walked around the area afterwards -- there's lots of cool public art, and also the World's Largest Vertical Garden.  (Little Singapore has it's share of big things!)
