For months, the most reliable summer entertainment on the Plaza was watching neighbors press their faces against the papered-over windows of the old Maya building at First and East Napa, trying to see what was coming. As of mid-July, the paper is down, the doors are open, and the corner has a name again. A block west, the restored bank at 497 First Street West is doing the same thing to a different demographic. Two of the four most visible corners of the square changed occupants inside a single quarter, which is not something that happens here often.
The short version for anyone who has been away: the team behind the girl & the fig has opened Dead Letter in the Maya space, and the Glen Ellen Star and Stella group has opened SMASH inside the Taub Family Outpost, with a second-floor cocktail room called The Beacon above it. Both are the work of chefs who already had Sonoma Valley zip codes. Neither is a chain, and neither reads as a tourist play. For residents, the interesting question is not whether to try them but what their arrival does to the shape of an ordinary August week on the Plaza.
First and East Napa: what replaced Maya
Maya sat on that corner for more than two decades before the owners retired. The building has a longer memory than that: at various points it held a post office, a medical office, and a clothing shop, and the postal echo is what the new occupants leaned into. Dead Letter opened on July 16, with John Toulze and Sondra Bernstein of the girl & the fig and Poppy as owners and Jeremy Zimmerman running the kitchen.
The physical thing to know is the grill. Zimmerman is cooking on a three-level Spanish charcoal setup that the kitchen team runs by feel, moving pork steaks, trout, and sweet corn up and down the heat like sorting mail. The dining room reads dark gray and burgundy with rugged stone walls, tall screens shifting surreal black-and-white images, a wooden postal window filled with vintage postcards, and an old Art-o-mat cigarette machine repurposed to dispense five-dollar artworks the size of a pack. It is a cocktail-forward room. Most of the large plates are designed to hit the middle of the table, which is a specific choice about how the room sounds at 8 p.m.
For a resident, the relevant shift is that this corner used to be a lunch and family-dinner stop and is now an evening room built around a hot grill and long tables. The Chartreuse-and-red-wine cocktails will not be to everyone's taste. The bigger point is that the Plaza gained a dinner anchor on the east side that it did not have before.
First Street West: what SMASH and The Beacon added
The other corner in play is the Taub Family Outpost, the 1910 Spanish Colonial bank building at 497 First Street West that underwent an extensive restoration and seismic retrofit before reopening as a multi-use hospitality space. As of May, the ground floor is SMASH, a fast-casual concept from Ari Weiswasser and Spencer Waite, the same team behind Glen Ellen Star and Stella. Weiswasser was a 2025 James Beard semifinalist. His new project sells smashburgers, fried chicken sandwiches, fries, shakes, and boozy shakes.
That is a real departure. Everything else the group runs is a full-service dinner destination with a tasting-menu sensibility. SMASH is deliberately quick: a short menu, fast turns, and outdoor seating on the square that takes advantage of the Plaza's open-container hours during the day. According to the Sonoma Index-Tribune's reporting on the building, the same team operates The Beacon upstairs as a speakeasy, and a rotating selection of The Beacon's cocktails is available downstairs at SMASH seven days a week. In practice, that means one door on the west side of the Plaza now covers a burger at 12:30, a shake for a kid at 3, and a serious cocktail at 9.
The corner had been dark for a long time before the Outpost restoration. Adding a counter-service midday draw to that side of the square changes how the lunchtime pedestrian flow works, especially in combination with Valley Bar and Bottle two doors down at 487 First West, which has been running its own coffee, brunch, and dinner rhythm since well before this summer.
What this does to the August calendar
Two new anchors on two different corners is a small fact. The reason it matters this month is that it lands inside an already crowded August. Sonoma Valley's summer calendar is not thin, and the Plaza is where most of it converges.
The scaffolding for the next few weeks looks like this:
- Sonoma County Fair, August 7 through 16 at the Fairgrounds in Santa Rosa, which reliably pulls Sonoma Valley residents north on weekends and thins out Plaza dinner traffic on Fair evenings.
- Tuesday Night Market on the Plaza, the Sonoma Valley Vintners and Growers-adjacent weekly ritual that runs through the summer and is the single largest recurring weekly event on the square.
- Sonoma Sundays on the Plaza, the free 2 to 5 p.m. concert series at the Grinstead Amphitheater presented by Music in Place and the City of Sonoma, running every Sunday from June 7 through October 4.
- Sonoma Shakespeare, outdoor performances of the classics on Plaza-adjacent grounds through August.
- Harvest Bell Ringing, which opens Sonoma Valley Vintners and Growers' 201st winegrape harvest and functions as the informal start of the working season for anyone who lives above a vineyard road.
The Plaza has always had a working rhythm rather than a tourist rhythm. What changed this summer is that the working rhythm now has two more places to end up.
The practical consequence is that the two corners fill different windows. SMASH is a lunch and family-dinner room with a bar option after dark upstairs. Dead Letter is an evening room. If the Tuesday Night Market pulls families to the Plaza from 5:30 to 8:30, SMASH catches the earlier end of that flow and Dead Letter catches the later end. On Sunday afternoons, the Grinstead concerts push people through the square from 2 to 5, and both new corners are set up to absorb the tail of that crowd rather than compete with it.
A working August rhythm for people who already live here
The question for a resident is not which new restaurant is better. It is how to fit them into a week that already includes farmers markets, concerts, and the tail end of the Fair. A few observations from the way the corners are set up.
Weeknight dinners at Dead Letter are going to be reservation-driven for a while. The room is not large, the opening press has been substantial, and the girl & the fig has a two-decade reservation habit trained into the local audience. Anyone trying to walk in on a Friday or Saturday in August should expect to wait or eat at the bar. Weeknights earlier in the week, and the shoulder hours around 5:30 or 9:15, will be the easier windows for the first six weeks.
SMASH is the opposite problem. It is designed for turnover, and the outdoor seating on the Plaza means the line is visible. The Beacon upstairs is where the same group is putting its bar-program attention. Residents who want the Weiswasser cooking without the counter-service format still have Glen Ellen Star up Arnold Drive and Stella in Kenwood, both unchanged. The interesting move is probably to use SMASH as a Plaza lunch stop before a Tuesday Market walk-through, then hold dinner reservations for one of the older rooms.
The Fair is the wildcard. From August 7 to 16, a meaningful share of Sonoma Valley households are north at the Fairgrounds for an evening or two, which means the Plaza is genuinely quieter on those nights than it will be later in the month. That is the window to try either new room without a reservation. After the 16th, both corners settle into whatever their real cadence is going to be, and the Harvest Bell will do the rest of the work of pulling attention back to the vineyards.
The larger point is that the square has not really gained restaurants this summer. It has gained two anchors on two corners that had been drifting, and both anchors are the second or third project of chefs who already live and cook in the Valley. That is a different kind of change than a national group opening a location. It suggests the Plaza's next few years belong to operators who are already here, working with older buildings that finally came back online.
