IME, everything in SF that young people might want to go to is packed full of young people who made reservations a couple of weeks in advance. Not a lot of venues for drop-in occasions that accommodate 6-20 people dipping in and out.
Edit: I can sort of imagine this happening at a bar with an unusually big patio, like SF's Zeitgeist. Not that Zeitgeist has a huge patio, it's just huge for the area. And if this gathering was always at a bar, I wouldn't go much, because I have a ton of trouble hearing people in bars.
