Sonoma Valley dining doesn’t get any finer than it does here, at this two-Michelin-starred restaurant set in Healdsburg’s Hotel Le Mars. The dining room—where the vaulted ceilings glow with golden light and where natty servers proffer selections from the caviar cart, cheese cart, and truffle humidor—encourages dressing up; and the sublime multicourse tasting menus from chef Douglas Keane (formerly of Restaurant Gary Danko) invite lingering. Look for dishes like Wagyu strip loin with leeks and Japanese winter squash; roasted lobster in a tamarind-ponzu sauce; and pumpkin tagliarini with truffled Pecorino. And opt for the pairings, especially if the 750-plus labels on the wine list make you dizzy. Reservations are required.
