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.
Some areas of San Francisco are so steep that the sidewalk literally is a stairway; other times it’s just more interesting to have a stairway between streets… or a slide. I once saw a grown man with a briefcase matter-of-factly go down this slide and continue on his way down the hill. Why not?
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.
