Just found out yesterday when I went in to refill my bottle of DaVero 30-Weight olive oil and buy 3 jars of their Indian Red Peach Jam.
Last day will be May 18. I didn't ask if they'd have any kind of special sale at that point. I used to work there (one of the original employees), so I know these folks and appreciate what they're going through, and didn't want to push for too much info.
For Bovolo fans, they will be staying (they have a separate lease). (As an aside, Zoi Antonitsas, former executive chef at Bovolo, who was recently a cheftestant on Top Chef, is filling in at Zazu out on Guerneville Rd.)
Copperfield's Books, which bought out Toyon Books next door some time back, will take over the Plaza Farms lease, knock down part of the wall, and it will become the bookstore.
So now's your chance to get some olive oil, preserves, teas, ceramics, etc at Plaza Farms, before they are no more.
