I had lunch at the DiTomaso winery. It was fine, but nothing special. The setting is the driveway of the winery, so not all that picturesque, particularly compared the restaurants of some of the neighboring wineries. I had one of the platos and a glass of one on their wines. The plato was a combination of some cured meats, cheese, a tapenade, some olives, and what was supposed to be pickled onions, but turned out to be whipped cream cheese (perhaps with some onion). The wine was ok, but the pour was small, particularly considering that the bottles are so cheap.
Other lunch options in the area are probably better.
