Just a block from the bright lights and bustling traffic of South Beach's Collins Avenue hides a secret little villa. If you're looking for it from the street, it's best to search with your nose and ears, not your eyes. An eight-foot-tall wall of greenery shields Casa Tua from view, but you can hear the gentle tinkle of glassware and the soft laughter of couples enjoying a wonderful meal before you even get a glimpse. Once inside, you're transported to the Amalfi Coast, perhaps Positano or maybe Sorrento. Step to the right and you'll find a seaside-chic dining room, where wicker chairs with cushions invite you to sit for a relaxing dinner. The open kitchen offers a chef's table that seats 20, perfect for watching your pasta being made from scratch as you enjoy a second bottle of wine. But the showstopper is the garden patio. Mature trees sway with myriad lanterns, each glowing with the soft radiance of a daydream. The effect is mesmerizing, festive, unfussy, and magical.
