You have a lot of hills to choose from in San Francisco but in my opinion the best (and most varied) views are from Bernal Hill. Bonus: from my kitchen table I can watch tiny blobs moving around on this hill-- slow blobs are people, fast blobs are dogs.
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.
One day when I was walking around in the hills behind my house, I happened upon this bizarre street. It was as though someone had taken postmodernism and tried to make it into a block of houses. Each one has its own internally complete theme, involving strange colors and sculptural elements attached to the outside walls (gold eggs, wisps of wrought iron). This led me on subsequent walks to name them: the Corbusier House, the Barn, the Preschool Blocks house, the House of Wicca… and so on.
