Some of the best entertainment can be found in the less beautiful areas. Behind Sacre Coeur is the famous Montmartre, this seems to be one of the oldest sections of Paris and lots of energetic activity can be found day and night.
Maybe because it was the older section of town and a place where poor artistic people gravitated to that the ambience became so festive. In anycase, the vigor can still be felt and shouldn't be missed.
