3 Best Restaurants in The Haight, the Castro, Hayes Valley and Noe Valley, San Francisco

This charming neighborhood trattoria is the only restaurant in the city exclusively serving Sardinian food. The island's classics are all represented—octopus stew in a spicy tomato sauce; spaghetti with bottariga (cured roe); and macaroni with sea urchin and cured tuna heart. Many choices on the extensive wine list are Sardinian. The staff is both friendly and efficient. This is not only a locals' favorite, but a restaurant industry one as well, so book seats in this unassuming spot in advance. Ask for a table on the lovely, light-speckled patio to set the mood for a romantic date night.

An offshoot of the restaurant Poesia next door, the name means "poetry" in Italian, and the pastries, desserts, and savory sandwiches at this café live up to the name. You can't go wrong with anything on the house-made cornetti or focaccia, or for that matter any of the wide variety of Italian pastries. The artful interior makes good use of tile and color, and the service is warm and personal.

This casual Italian wine bar hits all the right notes: the mood is convivial, the food is solid, and there's plenty of wine—more than 10 by the glass and a long list of bottles. The menu is straightforward, with assortments of Italian cured meats and cheeses, a selection of salads and vegetable dishes, and a roster of pastas and pizzas. Try the gelato: it will take you straight to Italy. A young, savvy staff fits right into the upbeat surroundings, with a marble counter, a handful of banquettes, and tables for two and four.
