Good lord, so much snark in this thread, so here's some actual suggestions if you want to enjoy yourself (note: I moved out 3.5 years ago). Get coffee at Four Barrel, Ritual, Sightglass, Blue Bottle, Philz Get tacos in the Missions at Taqueria Vallarta, Taqueria Cancun Go to Noisebridge, Sudo Room, Hacker Dojo Hike at Hawk Hill, Skeggs, Muir Woods, Mt.

Hang out in Dolores Park for the authentic SF experience. Also, El Farolito is the superior Mission burrito ducks
