Lorenzo, located at the epicenter of Collins Avenue madness, looks like something you'd see on Rome's Via Veneto. Chic chrome accents the inviting brown leather seating. An espresso and gelato bar anchors the dining room. The man behind the recipes is all old-school Chicago. Tony Mantuano has been turning out legendary meals at Spiaggia for probably longer than you've been alive, and he's brought his red sauce and gnocchi to South Beach. Meatballs ($14) taste like Grandma's, and a simple bowl of steaming spaghetti alla nadia is made with San Marzano tomatoes, fresh basil, and Parmigiano-Reggiano ($16). But if you want your socks blown off, don't miss the grilled octopus ($14), the most tender and flavorful you'll ever have. Save room for cannoli, made to order and filled with candied oranges inside the cream. A little Roman holiday, via Chi-Town, in SoBe. Molto dolce.
