Residential Mazarin is home to ornate, honey-colored 17th-century mansions fanning out from fountain-filled Place des Quatres Dauphins. A sizeable collection of paintings by Paul Cézanne and his Impressionist peers are on display in Musée Granet, while contemporary art hangs in the palatial Caumont Centre d’Art. Elegant restaurants with garden terraces serve foie gras, beef tartare, and duck to a sophisticated crowd.
