My drink of the moment. Not that you can tell from the photo itself, but it is a dirty chai. It is simply a chai tea latte with a shot of espresso. I don't know the exact origin of the dirty chai. I just saw Veronica Belmont mentioning it on her twitter. It made me want to try it. I've been ordering one at every coffee shop I've been to so far. La Boulange in North Beach has made the best one so far.
Anyway, try it and spread the word!
