"La Balle au Bond", Paris

This floating barge/restaurant is moored on the left bank of the Seine, at Quai Malaquais, very close to the Pont des Arts footbridge.  Across the river is the south side of the Louvre.

The title is probably an in-joke of its proprietors; it could be interpreted to mean "seize the opportunity".  In any event, you can get married on the boat.

I imagine that this is an excellent vantage point for watching the Parisian sunset while sipping your favourite cocktail.
