Those who haven't done this before or would happily repeat the experience could join in a stroll round Montmartre (with no cultural references to wear out brains, and with appropriate stops at watering-holes to raise morale).

This is because Chez Pradel is on that side of Paris.

But if others have a yen to stroll around some other part of the city, we can get the Métro as per Bernard's helpful post. Don't hesitate to make suggestions here asap.

PS to LEP: sorry this suggestion isn't really made for you. If you've an idea of a shorter stroll you feel you could do, fire away.
