Review copied from Frommers:
In the flood of publicity awarded to this hotel’s street-level restaurant, Le Louis XV , it’s been easy to overlook the equally elegant contender on the rooftop. The view alone is worth the expense, with the turrets of the fabled casino on one side and the yacht-clogged harbor of Old Monaco on the other. The decor is gracefully modern, with an ambience somewhat less intense than that in the self-consciously cutting-edge Ducasse citadel downstairs. Despite that, the place is undeniably elegant, with a two-fisted approach to cuisine that includes every imaginable sort of grilled fish (sea wolf, monkfish, sole, salmon, mullet, cod, or turbot) and meat such as Charolais beef and roasted lamb from the foothills of the nearby Alps. In summer and fair weather, the ceiling opens to reveal the starry sky. The cuisine is backed up by one of the Riviera’s finest wine lists, with some 600,000 bottles; the wine cellar is carved out of the rock below. Service is faultless but never intimidating or off-putting.
