6th and Market, San Francisco
6th Street, before the gentrification of South of Market, was considered a very run-down place full of drug addicts.
Today it still keeps much of that run-down feel, except that it feels authentic due to being less subject to the forces of gentrification.
Love the graffiti/art on the barricade. Beyond it can be seen Tu Lan, a well-known hole-in-the-wall Vietnamese noodle eatery.
