What are the best things to do with my mom in San Francisco?

My mom is coming out for a long weekend in April. Hopefully it won’t be raining! She is not super-athletic so hiking is kind of out, but maybe a short bike ride to the beach which I am already begging her to do. But other fun ideas? Good restaurants to take moms to? She isn’t the most adventurous eater, but she does like to go out to eat, she just isn’t into Indian food and that kind of thing.
