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.
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.
At the midpoint of the Filbert steps, near tourist favourite Coit Tower, The Malloch is a streamline Moderne gem built in 1937. I discovered it after watching Dark Passage, a 1947 Bogart and Bacall film noir. Lauren Bacall's character lives on the third floor and Bogey holes up there. A Deco beauty cruising towards the Bay. It has the coolest lift ever.
