Drive west on State Street past Ridley's Market and you will pass an empty lot with a construction rendering bolted to a fence. According to BoiseDev, plans for Anderson Prime American Steakhouse were announced in January 2025: a 15,000-square-foot, two-story destination restaurant with a butcher shop, a cigar bar, and a horseshoe-shaped bar behind the entrance.
While that lot waits, Star's Friday nights continue at businesses already open.
Plans for Prime American
BoiseDev reports that the Anderson family has run Anderson Reserve in Sweet, Idaho since 1947, and when Paul Anderson announced plans to bring a version of that restaurant to Star, he framed it as an expansion play: Sweet gets heavy holiday traffic but thin daily walk-in business, and Star offered a bigger population to build a butcher shop and full restaurant around. The Star City Council approved a development agreement modification for the site at 10206 W. State St., across from Ridley's, and Anderson said he hoped to open by June 2026.
The June 2026 target passed. By July 21, 2026, the project had passed design review with the city, which the team announced on Facebook after nearly two years of planning. But BoiseDev's records check that same month found no building permits filed with the city. Nineteen months after the first announcement, the project had cleared a planning hurdle and still had not started construction in any way the city could document. The restaurant opened its gravel lot for parking during the Star Fourth of July Parade.
None of this means the project is dead. Design review is a real step, and restaurants of this scale often take longer between announcement and opening than anyone predicts.
Friday Nights Along the Corridor
Half a mile from that empty lot sits Helina Marie's, a wine bar built into a restored 1930s cottage that Helen Collinson opened in 2004. It has weekly karaoke on Fridays at 8 p.m., along with line dancing and Blingo nights, plus a patio, a fire pit, and a tiki bar that has quietly made it the town's default second stop on a Friday. It is easy to miss if you are only looking for something new. It has been doing this work for over two decades.
The other anchor is the Star Riverhouse itself, at 960 S. Main Street. The city acquired the property in 2013 and finished improvements in 2019, turning a former private residence on the Boise River into public event space. This summer, the City of Star and the Southwest Idaho Business Alliance ran a free concert series there every other Friday from June through August. The rules catch first-timers off guard: outside food is fine, but alcohol has to come from the on-site vendor and stay inside the designated event area, and parking fills fast because the lot is shared with Freedom Park next door. Visitors can eat first at Rustic Table or pick up something from the Mercantile before walking in with a chair.
This year, the corridor's options included Helina Marie's weekly activities and the Riverhouse's summer concert series, alongside plans for Prime American.
What's Left on the Calendar Now
The concert series wrapped at the end of August, which means the corridor's fall lineup looks different but is not thin. A few things worth putting on the calendar:
- September 26: Firebird Raceway's Fall Automotive Swap Meet & Races, starting at 9 a.m. It closes out the season that opened with the Kruz-In 25th Anniversary Car Show back in June, and it is the kind of low-commitment morning that rewards showing up even if you have never been to the raceway before.
- October 13: Mayor Chadwick's State of the City and Liberty Hall Open House, where the city has announced a special guest: Idaho's own Liberty Bell.
- October 31: The city's annual Trunk-or-Treat at Riverhouse Pasture. The city is currently recruiting businesses, organizations, and individuals to host a trunk, so if your household wants in, that is an open door right now rather than a wait-and-see.
There is also a smaller, steadier layer underneath all of this: the town's regular civic rhythm. Mayor Chadwick holds a town hall on growth, traffic, and public safety every fourth Wednesday of the month at the Riverhouse, open to anyone who wants to ask a direct question about where the city is headed.
The Bigger Picture on State Street
Zoom out and the corridor includes a proposed restaurant alongside established local places. Prime American was still working through permitting nineteen months after its announcement. Meanwhile, Helina Marie's, a wine bar in a converted cottage, and the Riverhouse, a city-owned event lawn on the river, hosted activities during the summer.
Helina Marie's and the Riverhouse were already part of Star before Prime American was announced. When Prime American does open, whenever that turns out to be, it will be adding to a corridor that already knows how to keep people in town on a Friday.
That gives the corridor a story worth following beyond the restaurant's eventual opening.
