The Rooftop and the Accordion: What Actually Changed in Rohnert Park and Cotati This Year

The Rooftop and the Accordion: What Actually Changed in Rohnert Park and Cotati This Year

  • September 17, 2026

Two months apart this summer, two very different ribbons got cut five minutes from each other. In May, a Rockwell Group-designed rooftop restaurant with a four-thousand-bottle wine tunnel opened above Graton Resort and Casino. In August, the 35th Cotati Accordion Festival filled La Plaza Park with seven stages, forty-plus acts, and a parade called the Lady of Spain Ride-In. Same corridor, same summer, completely different scale of ambition. That gap is not a coincidence and it is not a contradiction. It is the actual story of this stretch of Sonoma County right now: Rohnert Park is spending like a resort town, and Cotati is staying small on purpose.

What actually changed at Graton

Graton Resort and Casino opened in 2013 with a chef roster built to prove dining could matter as much as the tables, recruiting Cyrus alum Douglas Keane, Martin Yan, and pizza champion Tony Gemignani, whose restaurant Tony's of North Beach is still on property. Thirteen years later, the resort just made its biggest culinary swing yet. In the latest phase of a $1 billion expansion, Graton spent $40 million on three new venues that opened in early May: a rooftop restaurant called AYA, a sports bar called Playbook, and an artisanal doughnut and dessert shop.

AYA is the one worth understanding in detail, because it changes what a night out in Rohnert Park can look like. The 28,000-square-foot space was designed by Rockwell Group with a full-ceiling skylight diffused by cream mesh drapery, sage green leather booths, and black-and-bronze marble tables. Diners walk through a wine tunnel stocked with more than four thousand bottles before reaching two terraces that look out over Sonoma Mountain. The restaurant has its own exterior entrance, separate from the casino floor and away from the smoking areas that have historically kept some diners away.

Running the kitchen is chef Roy Ellamar, who moved from Las Vegas with his wife Jennifer Murphy-Ellamar to lead the expansion. Ellamar grew up on the Big Island of Hawaii and is of Filipino descent, and the menu reflects it: ember-roasted carrots and coal-roasted swordfish sit next to koji black cod, wok-charred octopus, and a Filipino dessert called halo-halo. Most of the produce comes from a 40-acre farm two minutes from the restaurant, a detail Ellamar has said finally gave him the kind of culinary garden he'd always wanted.

Aya carries the meaning of life, breath and beauty.

That's how Murphy-Ellamar describes the name, and the restaurant leans into it: fire pits and heaters on the rooftop patio, a private dining room for sixteen, and event space that scales up to 180 guests. It is not a quick-bite kind of place. AYA is open Wednesday through Sunday only, with dinner service starting at 5 p.m. and the bar running until midnight on Fridays and Saturdays, and reservations already show it booking up around sunset, which is the whole point of the design.

Playbook, the sports bar addition, takes the opposite approach: wall-to-wall and table-mounted screens, thirty-eight in total, built for the game rather than the view. Between AYA, Playbook, the dessert shop, and the resort's existing lineup of 630 Park Steakhouse, Bistro 101, Boathouse Asian Eatery, and Tony's of North Beach, Graton now has more full-service dining under one roof than most small cities.

Cotati kept its calendar completely different

Drive five minutes into Cotati and the pace of change looks nothing like Graton's. There's no nine-figure expansion here. What there is instead is a steady run of small, chamber-driven openings that have kept La Plaza Park and downtown busy without anyone breaking ground on anything larger than a storefront.

Over the past several months, the Cotati Chamber of Commerce has hosted ribbon cuttings for:

  • Golf 20 FORE 7, a 24/7 indoor golf facility with high-tech simulators and private bays
  • Wildflower, which held its grand opening in April
  • Slow Co Pizza, celebrated with its own community ribbon cutting
  • A new location for Windows Health Clinic
  • Mercy Wellness, marking both a grand opening and its 15-year anniversary as Sonoma County's first licensed cannabis lounge

The city also finished the Sunflower Park improvement project this year, adding a new playground, a meditation garden, picnic areas, and lighting, and marked it with its own ribbon cutting rather than a press tour.

Then there's the Cotati Accordion Festival, which just marked its 35th year on August 15 and 16. Founded in 1991 by accordionist Jim Boggio and Clifton Buck-Kauffman after a bar conversation about one of Boggio's albums, the festival has grown into seven stages and more than forty acts spanning zydeco, polka, Tex-Mex, tango, and Parisian musette, capped off by the Lady of Spain Ride-In parade. Cotati takes the instrument seriously enough that it has an accordion sculpture in town. This is not a festival that scaled up to compete with anything. It scaled up because the town kept showing up for it.

The Cotati Farmers Market runs the same small-scale logic. Every Wednesday from 4:30 to 7:30 p.m., La Plaza Park fills with local growers, live music, and a dollar-for-dollar CalFresh match up to ten dollars, a detail that says more about who the market is built for than any marketing copy could. The 2026 season runs through September 25, which means there are still a couple of Wednesdays left before it wraps for the year.

The actual point of living in this corridor

It would be easy to read Graton's expansion and Cotati's ribbon cuttings as two unrelated stories happening to share a zip code. They're not. They're the same corridor pulling in opposite directions on purpose, and that tension is the actual value of living here.

Rohnert Park is where the big swing happens. A $40 million restaurant build, a Rockwell Group interior, a chef recruited straight from Las Vegas, a wine tunnel that would be at home in a much bigger city. If you want a night that feels like an event, the corridor now has one within a five-minute drive of most Rohnert Park addresses.

Cotati is where nothing needs to be that large to matter. A pizza place gets the same ribbon cutting energy as a health clinic. A park renovation gets a community event instead of a press release. An accordion festival that started as a bar conversation in 1991 is still filling La Plaza Park thirty-five years later, at the same scale it has always run, because scaling it up was never the goal.

Most Sonoma County towns pick one identity and commit to it. This corridor is unusual because it didn't have to choose. The resort-scale night out and the small-town Wednesday market exist four miles apart, and neither one had to shrink or grow to make room for the other.

What this looks like this month

If you want the rooftop version of a night out, AYA's patio is worth timing around sunset, and Wednesday or Thursday reservations tend to be easier to land than the Friday and Saturday slots that run until midnight. If you'd rather watch the game somewhere with more screens than seats, Playbook is built for exactly that.

If you're more of a Wednesday-evening-in-the-park person, there are still a couple of farmers market dates left before the season ends on September 25, and La Plaza Park is worth a walk-through even after the market wraps for the year, especially now that Sunflower Park's renovation is finished a few blocks away.

Neither version is more the "real" Rohnert Park or Cotati experience. They're both just what's actually here right now, at the same time, five minutes apart.
