Generator Paris, which is usually sold out, boasts a Summer rooftop terrace where guests can enjoy views of the Eiffel Tower and Sacré Coeur. This location, in Paris' lively 10th arrondissement, is a 5-10 minute walk to Canal Saint-Martin — one of the best spots for Paris nightlife. The design is playful and gives nods to trends in the area such as wooden booths and metro tile walls.
