Worth going just for the food. North West European cuisine is some of the best in the world, don't let generation Z spicy slop merchants convince you otherwise. In Paris you regularly find dishes that sound or look like something a half decent English country pub would serve, but elevated by superior ingredients and techniques. Also one of the best big cities for nightlife I've been to. Still loads of very laid back places frequented by locals and students even in the touristy parts. Far better than London in that sense.
