Downtown San Mateo is about to get a lot greener. Mixt, the Bay Area fast-casual salad chain, is set to open its new restaurant on March 3 and is rolling out a full week of giveaways, fitness tie-ins and neighborhood-focused events to mark the occasion. The San Mateo debut is the brand's 20th location and lines up neatly with the company’s 20-year anniversary celebration, with promotions and community activations running through March 8.
Where and when
The new spot lands at 301 South B Street in downtown San Mateo. Mixt lists the restaurant as operating daily from 10:30 AM to 9 PM, according to Mixt. On the chain’s site, the San Mateo entry is still tagged "Coming soon," sitting alongside its other Bay Area locations.
Opening-week giveaways and events
Opening week will not be a one-and-done ribbon-cutting. According to East Bay Times, Mixt plans a different promo every day:
- March 3: A free Mixt Baggu-brand bag and a complimentary Orangetheory class with an entrée purchase.
- March 4: A custom mini cupcake from Sibby's Cupcakery with an entrée purchase.
- March 5: A free first BodyRok class, plus entry into a raffle for a three-pack of classes.
- March 6: A pair of custom-engraved bamboo salad servers with an entrée purchase.
- March 7: A neighborhood scavenger hunt, dropping dog toys and free salads around downtown San Mateo.
- March 8: Postcards placed in the in-store mailbox that Mixt will mail out with postage paid.
The lineup turns opening week into something closer to a mini festival than a standard soft launch, with fitness studios, local sweets and even pups getting pulled into the mix.
A local milestone
Mixt first opened in San Francisco in 2006, and the company frames the San Mateo opening as part of its 20-year celebration, according to the brand’s website. The chain has been steadily spreading across the Bay Area, with locations in San Ramon, Oakland, Berkeley and Mill Valley, along with out-of-state stores, and it lists San Mateo as its 20th overall location.
What was here before
The salad shop is moving into a space locals know well. The storefront previously housed B Street Books, the independent bookstore that relocated to Burlingame in early 2025, according to the shop’s website. That move left a notable gap in the downtown streetscape that Mixt is now stepping in to fill.
The grand-opening promotions run from March 3 to 8, and most freebies require an entrée purchase, signups or in-person participation, so quantities and availability could be limited. For the full rundown and any schedule changes, check coverage from East Bay Times.
