This white-stucco slice of old-fashioned Riviera extravagance accommodates well-heeled guests in elegant, uniquely decorated (and sometimes quirky) rooms replete with swagged drapes and fine antiques (plus a few unfortunate "with-it" touches like those plastic-glitter bathtubs)—everyone should experience one night here. Built by Henri Negresco and opened in 1912, the landmark still epitomizes La Belle Époque, thanks to its marble columns, gilded ceilings, and qualité du Louvre collection of old-master art. Its awe-inspiring glass ceiling has even been listed as a historic monument; the hotel, however, has been reinventing itself following a massive multimillion euro renovation and in 2015, a third of the rooms were refreshed. The entrance hall (and the welcome) has lost its stuffiness in favor of a lighter design. Superchef Jean-Denis Rieubland, moreover, has added some modern touches to the menu at Le Chantecler (see Where to Eat). La Rotonde—complete with a carousel of painted wooden horses and a Folies Bérgère chandelier—is an over-the-top setting for lunch and dinner. For a touch of the Old Riviera, repair to the vintage walnut-and-velour bar (the best on the coast) for the cocktail of the month.
