Mango Day has built a reputation as one of the more reliably attended sapphic events in the city — less of a one-off and more of a recurring fixture, which means the crowd is familiar enough to make going solo workable without it being a project. The mixer format of Thots n Slayers is lower-pressure than a full club night if you're warming up for Saturday. Food and drink situations vary by venue; eat before the mixer, treat Mango Day as a drinking occasion rather than a dining one.
Practical note: queer day parties in SF tend to run in SoMa or the Castro corridor — BART to 16th St Mission or Civic Center covers most scenarios. Confirm before you drive anywhere; street parking in both zones on a Saturday afternoon is its own argument.
If you've only got two hours, go to Mango Day in the first hour when the room is still filling — easier to meet people, shorter bar line.
