International critics consider la Pergola the best restaurant in Rome for its outstanding menu by Heinz Beck and its superb view of Rome, from the precipice of Monte Mario. Nouvelle cuisine which changes seasonally and to Beck's whim caters to the glitterati of gastronome elite. The atmosphere and setting is elegant-- tromple l'oeil, marble, and masterpieces, and service is beyond exemplary. According to Frommers, the staff functions so beautifully they've been compared to a Viennese orchestra.
Though the menu changes seasonally, the water menu does not. Take a look, its definitely worth the wait.
