Inevitabilities of life include war, death, taxes, and the opening of fun, affordable, family-friendly Italian restaurants by the Belante clan. Luna Café is the latest venue from the family responsible for Bella Luna, Trattoria Rosalia, and Carpaccio, among others. Why do they keep starting up dining establishments? Because they're so damned good at it! Luna Café's atmosphere is comfortable; the service more professional than at much more expensive places; the menu's soups, salads, pizzas, pastas, antipasti, carpaccio, risotti, fish, chicken, and meats universally appealing. The Northern Italian fare, including standouts such as pasta e fagioli, lasagna, and a blistering wood-oven roasted chicken, are terrifically tasty, prodigiously portioned, and miraculously priced — pastas top out at $14, entrées at $22. Wait a minute — we have to make an update. Luna Café is not the latest Billante venture. Vivi Ristorante just debuted at First Street and Ocean Drive. Guess a South Beach branch was inevitable.
