This one’s easy to miss because it’s dwarfed by one of the many loud discount stores on Mission selling Day-Glo flowers and phone chargers. When you find it, the inside is tiny; there’s just enough room for you, an espresso machine, and a guy or two playing great music every time. And they have egg creams!
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.
