As far as I'm concerned, the best deal in town is Palio d'Asti. With every drink purchase you get a free pizza of your choice off a fairly well rounded menu. The Quattro Funghi with Fontina and truffle oil tops my list. The wines by the glass offer some interesting selections of harder-to-find Italian wines, and there is always the option of a classic martini. The atmosphere is fun and friendly, and as long as you keep drinking, the pizzas are yours for the asking; that is till 7 PM. -Excerpt from Happy Hours: A Heavy Hors D'oeuvres Round-up by Genevieve Robertson   Since 1990, Palio d’Asti has thrived as San Francisco’s favorite downtown Italian Restaurant by offering a seasonally changing menu, professional European service, a Wine Spectator recognized wine list and a premium bar. Private Dining Options for groups of 8-350 are available for breakfast, lunch, team building, cocktail receptions, and dinner.
