September Downtown: Festivals & Marketplaces

It’s been such an incredible, lively summer in Downtown San Mateo! In August, our neighborhood hosted the Downtown Express, the final concert of the Central Park Music Series, Central Bark, a Paw-fect Match Adoption Pop-Up Event, and HEAD WEST Marketplace.

September will bring fun fall events like a Movie in the Park, Dine & Discover Downtown San Mateo, two September Nights on B Street, the return of HEAD WEST Marketplace, and September Arts & Culture Fest.

Every month, our Downtown businesses host live music, comedy shows, dance parties, trivia, and karaoke.

Follow us on Facebook and Instagram so you don’t miss a thing. You can also head over to DSMA.org, which serves as your ultimate Downtown guide. There, you can explore our Events Calendar, Restaurant Guide, and a Historic Walking Tour. Our past newsletters are even hanging out in our archive. Thank you for continuing to show up for our small business community!
