The Corner Where Maya Used to Be Is Running Your Whole September on the Plaza

For most of the summer, the windows at First and East Napa streets were smudged with nose prints and handprints, cleaned nightly by an owner who kept a bottle of Windex within reach. Locals pressed against the glass trying to see what was replacing Maya Mexican Restaurant, the corner spot that had anchored that stretch of the Plaza for more than two decades before its owners retired. On July 16, the guessing ended. Dead Letter opened, and the building that spent 1896 to 1910 as one of Sonoma's early post offices became a dining room again.

If you already live here, you probably know the name behind it. John Toulze and Sondra Bernstein, the team behind the girl & the fig, took the space on the opposite corner from their original restaurant and built something that leans on a Josper charcoal grill instead of a French bistro menu. What's easy to miss, unless you're tracking the whole month rather than one opening, is how much of September on the Plaza runs through that same pair of names. Dead Letter is only the start of it.

A Restaurant That Finally Answered the Windows

Head chef Jeremy Zimmerman runs the kitchen at Dead Letter, working a three-level Spanish grill that handles pork steaks, trout fillets, and sweet corn at different heat levels, the same way a mail sorter would work a stack of letters. The menu is built for the middle of the table rather than individual plates: chicken karaage over tahini hummus, a strawberry aguachile with local rockfish, an Iberian pork steak with tomatillo crudo. Zimmerman put the intent plainly: "we're removing food envy." Toulze's version of the same idea was shorter: "let's have fun. Let's eat."

The building's post office history isn't just a name. Bernstein and Toulze sprinkled postal references through the space and layered in something else entirely: PROTO.logue, a digital art program Bernstein built from years of collecting work across platforms like Tezos, Foundation, and OpenSea. It's an unusual pairing for a Plaza restaurant, and it's part of why Dead Letter has already drawn attention from beyond the usual restaurant press.

Right now the restaurant is open Wednesday, Thursday, and Sunday from 5 to 9 p.m., and Friday and Saturday until 9:30. If you're used to walking up on a Tuesday night the way you might have at Maya, that won't work here. Reservations run through deadlettersonoma.com, and after a summer of curious foot traffic, tables aren't sitting open the way they might have in the space's quieter, post-office-turned-taqueria past.

Three Weeks, Same Fingerprints

Here's where the month gets interesting if you're the kind of resident who plans around the Plaza rather than just passing through it. September stacks two more events on top of Dead Letter's first full season, and the same names keep surfacing.

The Plein Air Festival is the odd one out here, and worth knowing about even if wine isn't your thing. It's been running since 2002, and this year's edition brings nationally recognized artists into town for a week of painting the vineyards, the historic architecture, and the light that makes this valley what it is. The work goes up for sale at a Friday gala and again at Saturday's free Art Show in Sonoma Plaza Park, and 40 percent of every sale funds K-12 art education grants across Sonoma Valley schools. If you've got kids in the district, some of that money likely already touched a classroom you know.

Then comes the Vintage Festival, now in its 129th year, running since 1897 when a local high school principal wrote a play about Bacchus setting the community's problems right. This year's theme is "Year of Community," and the schedule has grown into a genuine weekend: a 5K and a new one-mile Vintage Vines race kicking off Saturday morning, the Daytime Festival with live music and a wine garden on the Plaza, the Grape Stomp at the Plaza amphitheatre, and the Grand Tasting under the stars at the Sonoma Barracks with pours from up to 40 wineries.

The detail that ties the whole month together sits inside that schedule. The Harvest Dinner on September 25, set up as one long connected table wrapping the horseshoe driveway in front of Sonoma City Hall, is catered by the girl & the fig. Same kitchen, same ownership, now feeding a few hundred people at the valley's marquee harvest event less than three months after opening a second restaurant a block away.

What Actually Needs a Reservation

Not everything on this list requires planning ahead, but enough of it does that treating September as one loosely connected season rather than three separate outings will save you a scramble.

• Dead Letter takes reservations through its own site and is closed Monday and Tuesday, so a spontaneous weeknight dinner there won't work the way it might have at Maya.
• The Plein Air Festival's Friday gala on September 18 is a ticketed preview where the most sought-after paintings often sell before Saturday's free show even opens.
• Vintage Festival general admission runs $175 as of August, up from the $150 early rate that closed July 31, and the Harvest Dinner is a separate ticket at $250 that tends to sell out given the limited table setup at City Hall.
• The Grand Tasting at the Sonoma Barracks is a walk-around format with tickets sold both in advance and on-site, but the early-access option for a 30-minute head start before the general crowd is worth knowing about if you want time with the winemakers before the room fills.
• The Daytime Festival on the Plaza itself, including the Grape Stomp and the Artisans Festival, is free and open to the public with no ticket required.

Why This Is Worth Tracking as One Season

The easy version of this story is a list: new restaurant, art festival, wine festival, in that order. The more useful version is noticing that the same small group of people, largely the girl & the fig's ownership, is threading through nearly every major date on the September calendar. That's not a coincidence unique to this year. It's a reminder of how much of Sonoma's public life still runs through a handful of long-standing local businesses rather than outside operators cycling through leased storefronts.

For anyone who's lived here long enough to remember Maya on that corner, or who watched the Vintage Festival grow from a single afternoon into a four-day weekend, the throughline is part of what makes this place different from towns where the calendar resets every time a chain moves in. The building at 101 E. Napa Street has been a post office, then a Mexican restaurant for over twenty years, and now a charcoal grill with a digital art gallery bolted on. The people who run the town's biggest harvest dinner also just opened it. Knowing that doesn't change what you order at Dead Letter or which day you show up for the Grape Stomp, but it does explain why September on the Plaza feels less like three separate events and more like one long season with a consistent set of hands behind it.
