As in many parts of Miami these days, the restaurant scene is heating up in the Design District, with several new additions including Northern Italian entry Contessa Miami from the owners of Carbone, Dirty French Steakhouse, Sadelle’s and more. My Italian girlfriend who, when it comes to food from her country is the toughest critic I know, loved everything we had in a recent lunch. And I concurred. In fact, when lunching with her, the exact same menu at an earlier lunch was a repeat performance for me. In the “buzz” quotient department, Contessa  is taking on Swan, though the atmosphere is very different.
