We (my husband and I) are thinking about visiting Napa Valley however, we are kosher eaters. We hears that there is one kosher winery in Napa Valley. Is it still worth it to make the trip if we will not be able to drink or eat anything other than in that winery? We would also like to visit a spa and shop. Is there enough to justify a trip to the area? If so need recommendations for a beautiful hotel with spa.
