In the Mission, now as terminally hip as it was formally poor, the St Francis is a greasy good time since 1918. Stuck beautifully in the 50's both aesthetically and menu wise it's Americana in a bun. Dig in.
“You can taste the love” sounds like a cliché until you actually taste it and realize you are poor cynical human being who has never been to Alicia’s tamale stand! Especially on foggy days, these lovingly wrapped warm packages of deliciousness are indispensable.
This hole-in-the wall noodle shop reminds me a lot of Taipei, an unassuming place that pleasantly surprises the taste buds. San Francisco has endless amounts of amazing food, but this place stands out because of it's size, taste, and prices. There are only about 9 seats in the place but if it's packed, it's worth the wait. While you wait for your noodles or curry, they'll chop open a fresh coconut so you can hydrate yourself before downing a bowl of pure, salty goodness.
If you can get past the bourgie factor and/or you work down the street like I do, you will come to love this place. It has some of the best food in the city, a Blue Bottle coffee, and an observation deck from which you can watch the ferries come and go, emitting their weird beeps and disgorging tourists. The people who work here are great too (whether or not I dated a baker from the Acme Bread kiosk because of a Craigslist missed connection will be left to history).
