Good evening, and welcome to Alex Mak’s San Francisco Architecture Exposé Part 1 of 4.  In this series I learn about interesting buildings in San Francisco and then graciously tell you about them.  Its like Ricky Gervais’ show An Idiot Abroad, only I won’t be travelling anywhere and I steal most of my material from the internet.
