Something else handy you can pick up is a ‘Pariscope.’ You can buy one at any ‘Presse’ stand (and there’s one on every corner, and quite a few in the middle of the street as well… apparently Parisians don’t get subscriptions to newspapers) for only a few cents. It’s (in French) a listing of museum and other monument hours, prices, and locations, as well as upcoming events, movie times and places, restaurants, and more! If you have a bit of French it could come in very handy. A new one comes out I think it’s every Wednesday.
