No tips, but I have seen celebrities and tv personalities (like Anthony Bourdain) eat there. It looks amazing- - a once in a lifetime thing. Don't eat the day of! They'll have to roll you out of there after dinner - - from what I hear.
We just got back from that region last night. We had such a wonderful trip.
We stayed in Healdsburg first, then Santa Rosa, then we moved on to Belmont to stay with friends. Healdsburg was stunning. I wish we would have skipped the Santa Rosa part. Have fun on your trip.
