Producing some of the best food and wine in the United States, the rolling hills of the Napa Valley and nearby Sonoma are a magnet for gourmands and wine lovers. The vineyards may not be as extensive and the wineries not as grand as their European counterparts, but what Napa lacks in old-world traditions it makes up for with warmth and informality. Forget about snooty sommeliers and their pompous pretensions; here wine tasting is always a pleasure rather than a trial. With impeccable French-inspired cuisine, a benign climate and some beautiful scenery it’s hardly surprising that San Franciscans flock here year-round for some refined R’n’R.
