If you're looking to impress somebody, Healdsburg residents suggest Valette. The sleek American restaurant is regularly packed with suits and fancy ladies making a show of swirling their local wine (corkage fee is only $20) and ordering the multicourse 'trust me' tasting menu, where the gifted chef asks what you're into then decides what to feed you.
The scallop dish, which is baked within a squid-inked puffy pastry and bathed in caviar-studded Champagne beurre blanc, is otherworldly.
