It's at a new venue this year, SomArts (www.somarts.org), but the organizers fully expect it to sell out. Tickets are $25 in advance. Note the show was just moved up (yesterday) to 7pm-12 midnight for both Friday and Saturday
That's Friday March 1 and Saturday March 2, to be perfectly clear.
ThinBot will be there, looking quite a bit shinier than at his debut at BarBot 2012 (and there have even been upgrades since Gallifrey, if you saw him there).
