Two of Sonoma's most established restaurant families spent this year staring at the same three blocks of the Plaza and walked away with opposite plans. Chef Ari Weiswasser, who built Glen Ellen Star and Stella into destination dining, opened a counter-service burger stand where you order at a register and eat off a tray. Eight weeks later, Sondra Bernstein and John Toulze, the duo behind The Girl & the Fig and Poppy, opened a 65-seat reservation-only room built around a charcoal grill and a menu that changes with the season. Both restaurants sit inside century-old buildings you have probably walked past a hundred times. Neither one is trying to steal the other's table.
That's the part worth sitting with if you already live here. This wasn't two operators racing for the same customer. It was two operators reading the same stretch of Plaza and deciding it had room for two different clocks.
Same Block, Different Clock
SMASH opened at 497 First Street West in late May, inside the restored 1910 building that once housed a bank and, more recently, the Taub Family Outpost. Weiswasser, a French Laundry alum and 2025 James Beard semifinalist, built the concept as something closer to Gott's Roadside than Glen Ellen Star: self-serve ordering, communal tables, a small patio, basic burgers priced around $9 to $10. The buns come from Napa Baking Company. The produce comes from Glentucky Family Farm in Glen Ellen, which happens to belong to Weiswasser's father-in-law. Upstairs, the Beacon speakeasy now serves the full SMASH menu alongside its cocktail list, which means the same building runs a fast-casual counter on the ground floor and a slower bar scene one flight up.
The location matters more than it looks. SMASH sits steps from the Plaza's central park, one of the few spots in California where open container alcohol is legal, from 11:30 in the morning until sunset, every day. That isn't incidental to the concept. It's the concept. Order a burger and a boozy milkshake, walk it across the street, and eat on the grass. SMASH was built for people moving through the middle of the day, whether that's a family grabbing lunch between errands or a couple killing an hour before a winery appointment.
Dead Letter opened July 16 at 101 East Napa Street, on the opposite corner, in a building with a stranger history: it served as one of Sonoma's early post offices between 1896 and 1910, then spent more than two decades as Maya Mexican Restaurant before Bernstein and Toulze took it over. The new concept leans seafood-forward and cooks over a binchotan charcoal grill, with chef Jeremy Zimmerman running a kitchen built around shareable plates. The name is a wink at the building's postal past. The menu includes shrimp toast, chicken karaage over tahini hummus, a butterflied trout in red curry finished with cucumber labneh, and an Iberico pork steak with tomatillo crudo and hominy. It seats 65 people, takes reservations only, and opens strictly for dinner, five to nine most nights and until nine thirty on Fridays and Saturdays.
There's no lunch service at Dead Letter and no counter at all. You book ahead, you sit down, and the room stays dim and loud in the way rooms get when people are meant to linger.
Put the two side by side and the pattern is obvious once you see it. SMASH is built for daylight and speed. Dead Letter is built for evening and slowness. Between them, the two restaurant families that shaped Sonoma's dining reputation over the past two decades have effectively split the day rather than split the customer. If you live here, that's a more useful fact than "two new restaurants opened." It tells you that the same three blocks now function differently depending on what time you're walking through them, which changes how you plan a Tuesday afternoon versus a Saturday night on the square.
The Last Two Tuesdays
The restaurants aren't the only thing on a clock this month. Sonoma's Tuesday Night Market, the weekly gathering of produce stands, prepared food and live music that takes over the historic Plaza, runs from May through the end of August. With today's date landing in the middle of August, that leaves two Tuesdays before the market closes for the season, a detail worth knowing if a Tuesday evening walk through the horseshoe has become part of your week without you quite noticing.
Sonoma Sundays, the free concert series presented by Music in Place and the City of Sonoma at the Grinstead Amphitheater, isn't on the same clock. That series runs every Sunday from 2 to 5 in the afternoon through October 4, which means it will outlast the market by more than a month. If SMASH and Dead Letter split the day between daylight and dark, the Plaza's own calendar splits the summer the same way. One weekly event is closing out. The other has weeks left to run.
None of this is trivia for its own sake. A resident who treats the Plaza as a fixed backdrop misses how much it actually shifts week to week and even hour to hour. The market winding down doesn't mean the Plaza gets quieter. It means the crowd that used to fill Tuesday evenings will likely drift toward SMASH's patio or Dead Letter's bar instead, at least until the concert series carries the Sunday afternoons into fall on its own.
What strikes me most, watching this play out from a few blocks away, is how deliberately both new restaurants read the existing rhythm of the square before deciding what to build. Weiswasser didn't try to out-Fig the Girl & the Fig team. Bernstein and Toulze didn't try to out-casual a burger counter. Each read what the Plaza was missing at a specific hour and built for that hour alone. That's a more precise kind of local knowledge than knowing where to get a good burger. It's understanding that a town's downtown can hold two very different economic bets on the same block, at the same time, without either one cannibalizing the other, because they were never competing for the same seat.
I keep a running list of what opens, what closes and what quietly changes hours on the Plaza, not because I need another reason to eat well, but because these shifts tell me more about how Sonoma is actually living day to day than any single sale on Broadway does. If you're weighing what a move to this town might look like, or you already own here and want a sense of how the neighborhood keeps evolving in ways that don't show up on a listing sheet, I'd welcome the conversation.
