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.
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?
Adobe Bookshop brings me much happiness. Not only are there a zillion wonderful used books of all kinds, there is the man behind the books, Andrew McKinley. He is the heart and soul, and his wise, welcoming and super fun personality draws all sorts of colorful characters to gather and be eccentric.
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).
