Youcould almost call it a rite of passage — a dinner cruise on the River Seine aboard a glassroofed Bateau Mouche pleasure boat. Jean-sebastien Mouche casts off at 8.45pm (board by 8.15pm) from Pont de l’alma in the 8th arrondissement to the sound of piano and violin music. There’s a choice of two menus, the confidently named Excellence or Prestige, from j95 ($118), covering aperitif, and all the red-clothed tables have views. The round trip takes two hours and 15 minutes and while it is undeniably corny, there is an element of romance to it all. It is Paris, lights are twinkling, there is champagne. Pourquoi pas?
