Quick report. I went to Clementine a few weekends ago. It was a Saturday around 7pm. They have a full service bar, so it would be nice to pop in for lunch or dinner if you're a solo diner. The clientele seems older than Chapeau (one of my favorites).
I had a porcini mushroom ravioli, a roasted quail dish, and I forget the dessert. Wine list was okay, but I didn't look that hard at it b/c I was the only one drinking. I had a glass of their pinot noir, which was okay for a CA pinot. Prices overall were okay, but I think the service and food and price point is better at chapeau. And the wine list is truly interesting at Chapeau. Good points for Clementine is that the tables are more spaced out and not as loud as Chapeau.
Would I go back? Maybe once. I tend to like Chapeau more though.
