When the sun shines in Paris, people begin a frantic hunt for the best outdoor spots to spend their spring and summer evenings. In my opinion, few places will offer the range of the 25° Est next to the Bassin de la Villette.
Food? Yes, here it is cheap and copious. Music? Yes, regular concerts are held here. View? Yes, across the Bassin de la Villette, in a pedestrianised area away from exhaust fumes. Sun terrace? It has two!
Add to this two art-house cinemas nearby and the fact that Paris Plage (the inner-city beach) sets up here for a month or so in July and August, and you have the perfect spot for spring and summer!
