For those of you who prefer biking, Paris municipality has created Velib’; i.e. bike for rent with automatic rental stations located throughout the city.....Another way to sightsee Paris in spring.

Restaurants
The 5th and 6th districts of Paris are filled with small restaurants where typical French food is served, finding a place to eat cannot be easier. Be careful however with tourist traps (they usually wait at the entrance of the restaurant and try to hook you up) !! It is sometimes recommended to walk off the main streets to find a good “Brasserie” where price will be in relation with food and service. You can find many of them close to the Museum around Mouffetard street and in Les Gobelins area.
