One of the city of San Francisco's greats for rustic Italian meals, Delfina is nestled on a block of gems for food lovers, including Bi-Rite (and its creamery), Tartine Bakery and sister spot, Pizzeria Delfina. But even with this rarefied competition, Delfina continues to book well in advance and draws long lines for its few walk-in seats. The simple, yet lively dining room is attended to by a warm cadre of servers, and the bill of fare shifts with the seasons. Soul-satisfying dishes might include house-made francobolli with prosciutto and mascarpone, as well as perfectly roasted chicken with silky olive oil-mashed potatoes. Seasonal desserts, like a warm pear Charlotte with salted caramel and brandy-crème anglaise, are notably delightful.
