Starbucks at Laurel Height is open 24hr (California and Laurel St, http://www.yelp.com/biz/starbucks-san-francisco-132 http://www.yelp.com/biz/starbucks-san-francisco-132). It is hard to find seats before midnight, as it is full of students, but it is as nice as a starbucks get. Since it is so popular, starbucks tried to open another 24hr location close by, but there was a lot of opposition from local coffee places, so they didn't get a permit.
