I was pleasantly surprised to find a restaraunt with character and good food in Hayward. Buon Appetito has an authentic menu, great waitstaff, and decor to put you in an Italian village. I have been there several times for lunch and dinner, and I recommend for a hot date, a small group, or just a night out. Also has a full bar for after-work cocktails.
Pros: Good, authentic italian food, fast service
Cons: Quiet for italian
