Visitors to Nice could do worse than follow this guide by Leah Larkin in Stars & Stripes, the website of the US Military. Odd place, but good piece.
"France’s fifth largest city is the capital of the glamorous French Riviera. There’s plenty of elegance along the Promenade des Anglais, its seaside boulevard lined with palms and turn-of-the-century hotels and grand apartments. There are traces of North Africa in the tangle of dark alleys of Vieux Nice (old Nice). The outdoor markets and restaurants, as well as the numerous street stands, capture the flair of neighboring Italy. It’s an irresistible mélange."
