This Winter, Downtown San Mateo Pivots on Third Avenue and B Street

"Walk sign is on for all crossings."

The crosswalk signal at Third Avenue and B Street now says this out loud. If you press the button before your turn, it will periodically remind you to wait. The talking signal is the only one downtown. The City plans to see how it works at Third and B before deciding whether to add it at nearby crossings.

That choice of corner fits the rest of the season. The intersection the City picked for its test sits within a block of most of the new food announced downtown. The best-known business that just closed is a short walk north, in a building headed for a four-story rebuild. An evening downtown between now and the holidays will start and end near Third and B more often than not.

The Crossing the City Chose to Change First

The pedestrian scrambles at First, Second and Third avenues on South B Street all received changes this fall. Third Avenue got the most. According to the Downtown San Mateo Association's October 2026 newsletter, the City made four adjustments:

  1. New signs above the pedestrian signals and push buttons at First, Second and Third. Pedestrians cross on the "walk" sign. Green lights are for vehicles.
  2. A new signal order at Third Avenue. Pedestrians now cross before drivers on B Street get their green light.
  3. The talking signal at Third and B, which is being watched before the City decides whether to install it elsewhere.
  4. Extended crosswalk striping. Public Works crews ran the crosswalk lines all the way through the First, Second and Third Avenue intersections, so it's clear you can cross in any direction, including diagonally.

The City also plans more pavement markings inside these intersections and will keep monitoring all three crossings. If you cross at Third on your way to dinner, the sequence has changed. Pedestrians go first, and the diagonal is clearly marked.

Where the New Tenants Are Landing

Three food and drink businesses have announced downtown locations since late summer. Two are on East Third Avenue and the third is on South B Street, all within a short walk of the Third and B corner.

Business Address Former occupant Timing as reported
Roma Antica 172 E. Third Ave. Not reported Late-September target, per the Almanac in August
Pineapple King Bakery 145 E. Third Ave. Shabuway December 2026 target
Auntea Jenny 253 S. B St. Hereetea No date announced

Roma Antica has the most detail behind it. It's a Roman trattoria that opened in San Francisco in 2017. The Almanac reported in August that the San Mateo menu would be 95% the same as the original. The Almanac listed tonnarelli cacio e pepe at $21, suppli at $13 and pinsa Romana, an oval flatbread made from wheat, rice and soy flours, at $19 to $26. The space is about 2,000 square feet with a 10-seat Italian marble bar. It will open with beer and wine and add a full bar later.

In the same article, co-owner Alessandro Vasselli gave three reasons for choosing downtown San Mateo. The group already caters for companies in the area, many customers of the San Francisco restaurant live in San Mateo, and there aren't many traditional Italian restaurants nearby. The planned hours were 11 a.m. to 10 p.m. Sunday through Thursday and 11 a.m. to 11 p.m. on Friday and Saturday. Those were opening-plan hours, so check the restaurant's own channels before planning a dinner around them.

Pineapple King Bakery and Auntea Jenny were both in the Almanac's September roundup of Peninsula cafes and bakeries. DSMA linked that roundup in its own October newsletter. Each one is taking over a space that held a similar food or drink business, so the cluster around Third and B is filling with businesses of the same kind.

The B Street Corner That Stays Dark Until 2027

Farther up B Street, the corridor is losing a tenant. Donut Delite closed in September after 25 years of glazed doughnuts and bear claws downtown. The San Francisco Chronicle reported that the property owner had sold the B Street building. Donut Delite still operates locations in Redwood City and Menlo Park.

The City tracks the site as the 31–57 S. B St. commercial mixed-use development. The Daily Journal reported that Harvest Properties is overseeing the project with partner Preston O'Connell. The plan is a four-story, 41,200-square-foot building with retail, restaurant and office space, and completion is projected for 2027. The Daily Journal's article has the full project account. The paper's earlier coverage of the approval described ground-floor commercial space, offices on floors two through four, and a 55-foot building.

That leaves one stretch of B Street in a construction phase through the holidays, while the blocks near Third are gaining tenants.

Parking Around a Garage That Is Mid-Project

Driving in takes a little more planning this winter. Waterproofing work at the Main Street Garage runs from October 2026 through February 2027. Businesses stay open throughout and the elevator keeps running. The top level will close for about three weeks, and the City said in October that it would announce those dates once they were confirmed.

The free-parking hours help evening plans. City downtown parking is free on Sundays and after 6 p.m. every day. Private lots aren't included. At Pausa, the new bar menu is available until 6 p.m. in the bar area and outside, and all day for guests dining at the bar. If you arrive later, City parking is free and the bar seats still get that menu.

Central Park's Rink Fills the Same Evenings

San Mateo on Ice is back in Central Park from November 13, 2026, through January 10, 2027. The rink's site describes 11,000 square feet of real ice, open daily for recreational skating, parties and private bookings. It also lists four free Community Skate Days: November 16 and December 1, 8 and 10. The operator says sponsors fund hundreds of free tickets each year for local children through nonprofit agencies.

Evening skate sessions and dinner afterward both fall in the after-6 p.m. window when City parking is free.

A Late-Fall Calendar Within Walking Distance

These are the downtown dates and recurring nights after this post goes live, as listed by DSMA and the rink operator:

  • Friday, Oct. 30: Halloween Latin Night at Motion Arts Center and Ladies Bunco Night at the Peninsula Italian American Social Club.
  • Weekly nights listed in October: Bar Bingo at Blue Moon Bar on Tuesdays from 6 to 8 p.m., trivia at McGoverns on Tuesdays, karaoke at McGoverns on Sundays and Thursdays, and a Friday DJ set at O'Neill's.
  • Weekend mornings: Rise Woodfire serves brunch Saturdays and Sundays from 9:30 a.m. to 2 p.m.
  • Weekday lunch: Tai Er's Sichuan lunch combos run Monday through Friday, 11:30 a.m. to 2:30 p.m., at $25 for one or $55 for two. Thonglor Thai Bistro is under new ownership and offers a free Thai iced tea with any lunch entrée, Tuesday through Friday.
  • Friday, Nov. 13: San Mateo on Ice opens.
  • Third Saturdays: HEAD WEST Marketplace sets up makers and local merchants on B Street from 11 a.m. to 5 p.m. on the third Saturday of each month, which puts November's market on the 21st.
  • Saturday, Nov. 28: The Bougie Brunch at Golden Moon Studios.
  • December: Pineapple King Bakery's target month for 145 E. Third Ave.

On S. Claremont St., Takahashi Market at No. 221 marked its 120th anniversary in September.

The 31–57 S. B St. redevelopment, set for 2027, and the three tenants announced near Third Avenue are adding new space to the blocks around downtown homes.
