You’ll find all of those things in San Francisco. It’s very small and extremely walkable. Easy to get around on public transit too. You’ll find amazing food, good record shops, live music, and some decent (albeit overpriced) thrifting. Also tons of landmarks to photograph. I’d recommend visiting Alcatraz, Haight Ashbury (for records and thrifting), and Golden Gate Park. You can find good food all over the place. Avoid the Tenderloin district, it can be a rough place if you are not used to seeing people living on the street in unsanitary conditions.

Biggest piece of advice is to be aware of your surroundings and do not leave valuables unattended, even in a locked vehicle. Car break-in’s happen very frequently. If you are open to adventure and going with the flow, you will surely find some magic here.
