Top choice bar in The Mission, Dogpatch & Potrero Hill
Pink Elephants at Zeitgeist by torbakhopper

You've got two seconds flat to order from tough-gal barkeeps used to putting macho bikers in their place – but with 48 beers on draft, you're spoiled for choice. Epic afternoons unfold in the beer garden, with folks hanging out and smoking at long tables. SF's longest happy hour lasts 9am to 6pm weekdays. Cash only; no photos (read: no evidence).
