When you’re in Napa Valley, sipping wine from late morning until late afternoon, you’ll want to find the best places for lunch to break up the day – and the alcohol. Much depends on where you happen to be and where you plan to head next on your Napa Valley wine tour. Maybe you’re based in Napa but find yourself in Yountville after a tasting at Domaine Chandon. Or you want lunch in St. Helena before an afternoon tour at Castello di Amorosa. Maybe you find yourself closer to the town of Napa. Because the Napa Valley is an agricultural area with only a sprinkling of towns, you need to plan, especially since many restaurants require reservations even for lunch.
