Dining in the five villages of Cinque Terre is generally a relaxed, "coastal chic" affair. Unlike the formal dining rooms of Milan or Rome, the atmosphere here is breezy and informal, reflecting the rugged, seaside environment. For men, a pair of well-fitted dark jeans or chinos paired with a linen shirt or a polo is perfectly acceptable for most "trattorias" and "osterias." For women, sundresses, midi-skirts, or stylish trousers with a nice blouse are common choices. The most critical advice is to wear comfortable footwear, such as dressy flats, loafers, or high-quality sandals; the steep, cobblestone streets and narrow staircases of villages like Vernazza and Riomaggiore make high heels nearly impossible and even dangerous to navigate. While you don't need a suit or a formal gown, Italians value "bella figura" (looking good), so avoid wearing workout clothes or beachwear like flip-flops and tank tops to dinner if you want to blend in with the locals.
