To keep your love fire burning, take Mr. Right to our new favorite casual restaurant, Rosinella. Discreetly situated at 525 Lincoln Road., this clandestine Italian restaurant will make you feel like you stumbled into a cozy European eatery where no one knows from house music and cell phones." "Rosinella is all about dressed-down couples sharing wafer-crust Margherita pizzas and hushed conversations. And talk about cost-effective: Our hungry-girl order of carpaccio di manzo and penne arrabiata totaled $16.95, which, on South Beach, is, like, free."
