10 Best Restaurants in Napa and Sonoma, California

A vaulted wood-beamed ceiling and paper-topped tables set the scene for romance at this softly lit French bistro inside an 1890s boathouse. Look for clever variations on classic dishes such as croque monsieur (grilled Parisian ham and Gruyère) and salade niçoise for lunch, with veal sweetbreads, cassoulet, beef bourguignon, and, in season, mussels steamed in aromatic fennel, white wine, garlic, and thyme for dinner.

Escargots, cassoulet, steak au poivre (pepper steak), and other French classics are prepared with precision inside this tan-brick country bistro whose flower-filled window boxes, extra-wide shutters, and red-and-white-striped awning hint at the old-world flair and joie de vivre that infuse the place. Regulars often start with the rich tomato soup in a flaky puff pastry before proceeding to sole meunière or coq au vin, completing the French sojourn with crème brûlée or other authentic dessert.

The team that created The French Laundry is also behind this place, where everything—the zinc-topped bar, antique sconces, suave waitstaff, and escargots, French onion soup, and salmon and beef tartare starters—could have come straight from a Parisian bistro. Sole Provençale, pan-seared flat iron steak with caramelized shallots, and mussels steamed with white wine, saffron, and Dijon mustard—the latter two served with crispy addictive fries—are among the perfectly executed entrées.

Youthful vacations in southern France inspired the menu at the wide-windowed storefront restaurant opened by Nick Ronan, a longtime San Francisco restaurateur and author of The Kissing Chef. "I feed my soul through people," the chef has been known to declare, his zeal for community informing his effusive hospitality and diligent Cal-modern reinterpretations of onion soup, cassoulet, coquilles St. Jacques, beef Bourguignon, and other familiar fare.

Inside an ivy-laced old stone building and with good reason atop many a Napa Valley visitor's bucket list, chef Thomas Keller's destination restaurant generally lives up to the hype with intricate yet not overthought cuisine. Some courses on the two prix-fixe menus, one of which highlights vegetables, rely on luxe ingredients such as white quail or shima aji (striped jack); others take humble elements like carrots or fava beans and elevate them to art.

At this hot spot for inventive French cooking inside the historic Sonoma Hotel bar, you can always find a dish with the signature figs on the menu, whether it's a fig-and-arugula salad or an aperitif blending sparkling wine with fig liqueur. Also look for duck confit, steak au poivre, mussels and frites, and wild flounder meunière.

The strip-mall location a mile southeast of Windsor's town green only adds to the cachet of this what-a-find combination charcuterie shop and bistro whose croque monsieur a local magazine anointed Sonoma County's best (madame's mighty fine, too). Chef-owner Marc-Henri Jean-Baptiste's Haitian-French roots, training under culinary icons Daniel Boulud and Alain Ducasse, and affinity for his local purveyors' "European mentality of respect for the environment and traditional agriculture practices" all inform Maison Porcella's dreamy cuisine.

Conceived as a gathering spot for cocktails, conversation, and clever riffs off classic French cuisine, this restaurant named for the fin de siècle chef extraordinaire Auguste Escoffier combines clubby comfort with drawing-room sophistication (pay attention to the wallpaper selection). Escargots five ways, filet mignon tartare, and salad Lyonnaise set the stage for mussels and frites, beef-cheek bourguignon, salmon à la plancha, and Parisian gnocchi rendered with 21st-century panache.

Breakfast, served through lunchtime at this bright-yellow French-style bakery and café, includes the signature omelet (sun-dried tomatoes, bacon, spinach, and Brie) and French toast made from thick slabs of cinnamon-walnut bread. French onion soup and cranberry-turkey, chicken with Jarlsberg, and (on the cinnamon-walnut bread) Monte Cristo sandwiches are among the lunch favorites.

The compact menu at this cheerful bistro focuses on California and French comfort food—pot roast and duck confit, for instance, as well as flounder meunière and a few thin-crust pizzas. Steamed mussels are served with crispy fries, which also accompany the Chef's Burger (top sirloin with cheese), two of the many dependable dishes that have made the Fig a downtown Glen Ellen fixture.
