If you're looking for street festivals, the To Life! festival is going on in Palo Alto. I love this event!
This annual event that showcases the diversity of Jewish culture through art, music, dance and food. It celebrates of art and community, welcoming people from a variety of backgrounds who want to honor Jewish heritage and learn about the many community resources offered by Bay Area Jewish organizations.
It's also very family-friendly, with crafts, a bounce-house area and music on several stages. It's this Sunday, October 10 on California Avenue in Palo Alto. If your near a Caltrain line, take that. Extra fun for the kids, and the fair is just a block off the California Street stop in Palo Alto.
