National street-food chronicler VendrTV was in town sampling java at the Blue Bottle kiosk in Hayes Valley, and has just posted the video. Lovably geeky host Daniel Delaney shares a cup with Facebook's Dave Morin (something brainy about the intersection of street food and social networking), and chats up Blue Bottle owner James Freeman. The essential bit? Freeman describing how the Linden Street kiosk came to be, transforming what he calls a "pee-smelling alleyway" into an urban coffeescape worthy of, say, London or Melbourne. We love that.
