Things to do or places to see by yourself on a Monday night

Hey Bay Area people, I'm a NZer on holiday here in SF and by myself for tonight. Wondering if anyone has some decent suggestions for things to do by yourself around here. Do people around here go to bars by themselves to meet people?

¯_(ツ)_/¯

Any suggestions appreciated! Oh, and I'm a 23 year old bloke if that maters
