So, the Inner Richmond. The Inner Richmond is like, the real Chinatown, and I'd start there.
If it's a naughty day, I'd go to one of the fast food-y dim sum places: Good Luck Dim Sum. It's the kind of place where if you take too long, you get yelled at by the ladies, and there are like seven wobbly tables. The soy sauces comes out of ketchup bottles. It is low key. I'd be there to get the sticky rice with chicken, in lotus, which is like $2. You can have that and a cup of porridge, and it's super good and super hearty.
The original Green Apple Books on Clement St. is full of handmade signs and book recommendations.
There's a really good bookstore down the street, Green Apple Books--both new and used. There's an annex to that, which also has periodicals. They've opened up another store that's next to Golden Gate Park.
I always see people in Golden Gate Park and they're just on their phones. You know, it's like, don't sit on your phone and be in the park. Walk to Green Apple, and buy yourself a book and read it in the park. It's one of those places where they're always playing weird music, like Japanese death metal or something. I am a huge fan of all the cultural institutions in Golden Gate. The De Young is great, so if you have a friend with a membership, go with them.
After that... I don't go that often, but there are farmer's markets everywhere. Everywhere. Like, there's one in front of the Kaiser Permanente. If you don't have a chance to get out of the city around San Francisco, go to one of the farmer's markets. It's a good representation of why California people are so spoiled when it comes to food.
