Frogs could fall from the sky. We could be down to our last rations, holding on to hope by a fingernail. And Monique Siu would still make sure we had a lovingly crafted meal, delivered with great bread, a beautiful glass of wine, and proper service. For 25 years on SE Hawthorne, as keeper and guardian of three of Portland’s most storied restaurants, Siu has never wavered from her mission: to bring art and beauty, ideas and grace to the table.

But all things must pass, as George Harrison reminded us. Over the weekend, Siu—one of the founding members of the iconic Zefiro in the 1990s—posted on Instagram that she’s waving the white flag: OK Omens, the eight-year-old wild child offspring of her late, legendary Castagna and Café Castagna, will serve its last meal on October 17. “I am officially wrapping up this chapter and heading into retirement,” wrote Siu.

When the door shuts, we’ll wave goodbye to one of most significant restaurateurs in Portland’s history. And to a way of life—an utter graciousness, a conviction, an intelligence on the plate. Siu was one of our great talent scouts. She discovered or championed ambitious cooking in a DIY seat-of-pants city. Davenport’s Kevin Gibson, Olympia Provisions’ Elias Cairo, and two-star Michelin chef Matt Lightner graced Castagna’s kitchen. In 2018, she opened OK Omens as a wine-bar playground. The idea was to cut loose Castagna’s young guns—rising-star somm Brent Braun and cerebral Castagna chef Justin Woodward, who departed in 2024, then died, tragically, the next year. She even let them come up with the oddball name. It was a bit of joke: good omen, bad omen, OK omen, meaning you never know what the future holds. 

Current chef Joe Papas is not a household name. But he was on his way, as one of the city’s most exciting young talents. It took a few years for OK Omens to find a groove and identity. Braun’s zine-like wine list and quirky obsessions earned James Beard Award semifinalist nominations for Outstanding Wine and Other Beverages Program in 2023 and 2024. Food swerved from fried chicken to modernist sweets, including Portland Monthly’s Dessert of the Year in 2022, Woodward’s brilliant “kind of banana split.” But under Papas, the menu felt more cohesive, with fresh urgency and word-of-mouth traction. The 34-year-old industry vet made local food taste fresh again. Prepping an upcoming update for our restaurant listings, I was on the verge of calling it a Northwest sleeper with what could be the city’s best bistro burger (see below).

“That’s the irony, we were finally getting there,” Siu says, with a laugh. But the challenges finally became too great, even for someone who, against all odds, weathered the Great Recession, Portland’s willful resistance to fine dining, and the pandemic. “I’m happy the message about retirement came first. But there’s so many factors. The restaurant scene is so different than the one I came into. Things haven’t been right since COVID, when I felt the effect and closing of Castagna, the effect on Justin. I don’t think the industry has really recovered from how it changed everything.”

Finances certainly factored into the decision. “I don’t mind if people know we were struggling,” she adds. “It’s very hard to make an independent restaurant work with the quality I want. Joe is such a talented guy. Most young chefs don’t have his enthusiasm for ingredients. But we can’t charge enough for them.” 

“The farm-to-table bubble is bursting,” says Papas. “The economics have always been bad. But it’s too expensive to source now. We’re back to being a food cart city.” His next move is to Tillamook as chef at Bayocean Oyster House, an intensely local seafood restaurant slated to open next summer by his mentor and friend Jacob Harth.

What does Siu hope the world will remember about OK Omens? “It was really a fun, interesting collaboration, originally with Justin and Brent at first. Katya Pearl, our front of the house since the beginning, brought it alive. She loves hospitality and service. Brent brought Riesling to people, changed their palates. It was a great opportunity to work with these young, cool people, like Joe.”
