The Fillmore Corner of Alamo Square Was Dark for a Year. Here's What Finally Took It Over.

For 28 years, the corner of Fillmore and Grove was Alamo Square Seafood Grill. Snapper, salmon, tuna, swordfish, and petrale sole, all sold by the half pound at the same price, all the way through until fall 2024. Michael Bauer, reviewing it years ago, called it "good seafood value at Alamo Square." That kind of consistency, the same fish counter running through three decades of the neighborhood changing around it, is its own kind of landmark, even if nobody put it on a postcard next to the Painted Ladies.

Then it closed. The space sat empty through the rest of 2024 and into 2025, a remodel underway but no restaurant open behind it. By August 2025, word had gotten out that a Friulian trattoria called Polenta was coming to the address, with a significant remodel already in progress. It still took another nine months for the room to actually open. Polenta Trattoria Friuliana didn't soft-open until May 2026.

That gap matters more than it looks like it should. For a year and a half, the Fillmore side of Alamo Square had no restaurant of its own while Divisadero, one block over, kept adding them. What finally filled the space wasn't another version of what's already thriving nearby. It's a narrow, specific bet on a region of Italy most diners here have never eaten from, and that bet is now the reason this side of the park has a Tuesday-night reason to exist that it didn't have a year ago.

What Was Actually There Before

Alamo Square Seafood Grill wasn't a destination room. It was a neighborhood fish counter with a "bring your own wine" night and corkage waived, the kind of place regulars book without checking a website first. Bauer's old line about the owners being "veterans at offering good food at great value" was accurate for a long time. When it closed at the end of 2024, it took with it the only sit-down restaurant on that stretch of Fillmore, leaving the Divisadero side of the neighborhood, with its produce stands turned coffee bars and its dozen-restaurants-in-a-year growth spurt from the late 2010s, as the only real dinner option within walking distance for anyone on the park's east side.

The Delay Tells You Something the Opening Doesn't

Nine months between a name getting out and a room actually opening isn't unusual in San Francisco, where remodels and permitting rarely match anyone's early guess. But the specific shape of this one, a known concept and a known address sitting mid-renovation for the better part of a year, means the neighborhood spent from late summer 2025 into the following spring anticipating a restaurant that kept not showing up. That's a different texture than a storefront just sitting vacant with no explanation. People were watching this one.

What they got, when it finally opened, wasn't a hedge. Polenta Trattoria Friuliana is built around Friuli-Venezia Giulia, the region where Italy, Slovenia, and the old Austro-Hungarian border used to meet, which is why a restaurant with an Italian name serves goulash and buckwheat blecs alongside prosciutto San Daniele aged 36 months. The owner, Giulio De Monte Gaspardo, is a former sommelier at Bottega in Yountville who says he personally knows the winemakers behind most of the bottles on his list. The chef, Michele Gargani, was born in Friuli. The dish to start with is frico, a warm potato cake layered with onions and Montasio cheese. From there the menu moves into potato gnocchi under a ragu of housemade Friulian sausage, and a plate of asparagus with prosciutto and a fried egg that reads more like a Central European breakfast than a trattoria appetizer.

It is a small room. It is not trying to be the next Che Fico. It's the kind of restaurant that exists because one person spent years learning a specific set of vineyards and decided the Fillmore corner of Alamo Square was where he wanted to pour them.

Divisadero Didn't Need Another Restaurant

The contrast only lands if you know what Divisadero already looks like. Nopa opened there in 2006 and reset how people thought about the corridor. Che Fico followed in 2018. Bar Crudo, Souvla since 2016, Little Star, 4505 Meats, Fool's Errand. At one point, a dozen new food businesses opened or announced plans within a single year on the half-mile stretch between McAllister and Page. That density is exactly why a genuinely new restaurant one block east, on the quieter Fillmore side, doesn't read as more of the same. It's not competing for a seat at an already crowded table. It's the first sit-down option that corner has had since the fish counter closed.

What Else Is on the Calendar This Fall

Two other things anchor the neighborhood's fall rhythm, and both are recurring rather than new.

• The Divisadero Art Walk happens four times a year, in March, June, September, and December, turning the corridor's small galleries into a single walkable evening. Lake Gallery, upstairs at 661 Divisadero with its entrance on Grove, has been part of the walk since it opened above Plant It Earth. Rare Device shows work. Fly Bar and Madrone Art Bar bring live music into the rotation. It's the one night each season when the Fillmore edge and the Divisadero spine feel connected rather than separated by a park.
• The Alamo Square Flea Market, hosted by the Alamo Square Neighborhood Association along Scott, Fulton, and Hayes streets, has a history of skipping years entirely when park construction gets in the way. It's the kind of event worth checking for on the ASNA calendar before assuming it's happening on the same weekend as last year.

The city's Sundown Cinema program, for what it's worth, skipped Alamo Square entirely in its 2026 lineup, choosing Mission Dolores, the Presidio, and Marina Green instead. Whatever outdoor movie nights happen this year, they won't be happening in this park.

The Corner Has a Reason to Stop Now

None of this adds up to a neighborhood transformed. It adds up to one long-vacant corner filling with something specific instead of something safe, timed alongside two recurring events that were already part of the neighborhood's calendar before Polenta existed. For a year and a half, the Fillmore side of Alamo Square was a place you walked past on your way to Divisadero. Now it's a place with its own wine list, its own chef, and its own reason to stop before you get there.

If you own property near this corner and you're curious what a shift like this tends to mean for a building's foot traffic or resale interest down the line, that's exactly the kind of on-the-ground detail the Bonn Webb Team tracks when we walk owners through a complimentary, confidential valuation.
