Be prepared to dine like Parisian royalty when visiting the Michelin rated La Tour d’Argent, or “the Silver Tower,” which claims to have once been frequented by King Henri IV. Established in 1582, impeccable views of Notre Dame Cathedral and the Seine can be enjoyed alongside some quintessential French fare — roast duck (which are raised on a private farm and come with a numbered certificate), pâté and fish. The restaurant even inspired the 2007 film “Ratatouille.” The wine cellar — one of the best in the world — survived World War II and is guarded around the clock. It houses more than 450,000 bottles detailed in its 400-page wine list. In its ornate salon, diners can expect over-the-top formal service and opportunities for celebrity watching.
