Some of that....and whatever my friend wants to do.
Well it's worth doing the night tour of Alcatraz, if it's available. That might be a seasonal thing though, not sure. If you have an interest in science, the Exploratorium is kinda cool. It's geared towards kids but there's all sorts of stuff to try out even as an adult. I went when they were serving booze there for an "adults night" and had a blast.
Golden Gate park is big, cool to see. They have a bunch of nice walking areas and the California Academy of Sciences in the center. There are often people with RC boats and those tiny sailboats on the little manmade pond thing in there. If you start in the end facing the center of the city, on the opposite end is Ocean Beach (what a name) with a nice view and the old bath houses. They also had fire pits you could sit at and light up a fire at one point, not sure if that's still available or not. Don't expect to swim anywhere in the ocean though, it's cold as fuck.
It's worth seeing Pier 39/Fisherman's Wharf, there's a lot of touristy stuff there. That should satisfy your souvenir and gimmicky restaurant needs. Make sure you try Trish's Mini Donuts.
Right now the Stranger Things Experience is going on, I haven't done it yet, but the gf and I are going out there to check it out one of these weekends.
You can go to Ghirardelli Square and get a free chocolate and do a tour. There's Twin Peaks which is a weird drive up, but it's a beautiful view of the city, especially at night. The Stinking Rose is a unique garlic themed restaurant, worth checking out.
I'll be honest, I don't live that far from SF, but I haven't been there in like a year due to COVID pretty much having everything closed down. When I was looking up a lot of cool smaller bars and restaurants, most of them seem to be shut down now, which sucks.
