I liked the idea of the Café des Techniques at Musée des Arts et Metiers. Even if we don't have international visitors this time around it makes for a nice and topical meeting point.

as the group seems to be a small one, why not stay in one place

Are you saying that walking is better in large groups than in small ones? My experience says the opposite. (Walking favors small conversations, sitting favors large ones.)

Bonjour Everyone,

If you want to walk, no particular suggestions but as the group seems to be a small one, why not stay in one place for a starter?
