Hi Nicotum,
too bad you would not stay one more week, otherwise you could have visited us at the Division Malakoff, local ASL club.
Other than that, if you feel like doing some shopping, few shops are still selling wargames, the one selling the most ASL stuff being Descartes, Meissonier street.
And if you are looking for a game, I bet you can easily find a host here.
I hope you will enjoy your stay in Paris!
