"Pack a Picnic from Oakville Grocery Take advantage of the Mediterranean-like climate in Napa Valley (it rarely rains between May and October) and pack a picnic — without compromising on the quality of your cuisine, of course. The Oakville Grocery on Highway 29 has been supplying travelers for over 100 years, although under its new owner, Leslie Rudd of Dean & Deluca, the offerings have become decidedly upscale. Specializing in California cheeses, charcuterie, a good selection of local wines and nicely prepared seasonal salads and sandwiches, pack a picnic for your next tasting appointment or enjoy the impressive view of Opus One from one of the tables outside the Grocery."
