La Tour d'Argent
This legendary Michelin-starred restaurant and its setting overlooking the Seine remains magnifique; if you don't want to break the bank on dinner, treat yourself to the somewhat cheaper four-course lunch menu. This entitles you to succulent slices of one of the restaurant's numbered ducks (the great duck slaughter began in 1919 and is now well past the millionth mallard, as your certificate will attest). Don't be too daunted by the vast wine list—with the aid of the sommelier you can splurge a little and perhaps taste a rare vintage Burgundy from the extraordinary cellars, which survived World War II.
