Head to Santé for a splurge-worthy date night of Californian-inspired French food inside Sonoma’s fanciest hotel. Focus on the interesting starters like salt-roasted baby beets with macadamia tofu and glazed quail with grapes and fennel pollen, and throw in a mustard-crusted rack of lamb to share. The dining room is just as upscale as the menu, with a glass-walled wine vault stocked with a mortgage’s worth of wines as its centerpiece.
