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 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.
Here is another place packed with visual stimuli, along with weird smells and busy sidewalks. I love roaming through all the shops, venturing deep down the aisles to hunting for all things odd and unknown. So much to see, I wish I had extra eyes!
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?
