"It was always a partnership between them and Bruno's, and it was a mutual agreement to move on," she said, suggesting that, despite racking up sparkling reviews, Ostler and Zacher's food just wasn't bringing in the business. "It just wasn't sustainable, didn't produce enough interest on their side or on our side."
Still, Gaebe said, she's proud of what the chefs accomplished.
"They're excellent chefs, they put together an amazing menu," Gaebe said. "They're really nice people," she added.
Before Ostler and Zacher's tenure, Bruno's hosted a Thursday night pop-up marshaled by current Bar Tartine chef Chris Kronner. Gaebe said Bruno's had found a niche in what she called the pop-up "nonstaurant," and was seeking a chef-partner able to carry on the tradition. She said she hopes to have food service back at Bruno's in a month.
