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.
Murals! where? everywhere! walls, streets, signs, windows. keep your eyes peeled. I walk a lot in San Francisco and always seem to find new murals in the least expected places. They are a constant source of inspiration, and make me wish I could paint worth a damn.
Gorgeous view of the city in this park/permanent festival! Any beautiful day of the week you will find so many picnickers, hula hoopers, cute dogs, gay boys in their skivvies, ganja cookie salespeople, crazy weirdos and can collectors, it feels like a neighborhood concert is going on! My kind of place, for sure.
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.
