Hello.  One day I hope to eat at a Parisian cafe.
Yes, me too! Parisian cafes serve as a center of social and culinary life there
That sounds amazing.  Do people take long lunches there?
Yes, the cafes show the Parisian way of sitting undisturbed for a couple hours, just watching the world around them 
That sounds relaxing.  What kind of food would they serve for such a long lunch?
Generally they have a complete kitchen offering a restaurant menu with meals for any time of the day, as well as, a full bar
I can almost imagine being there.  Do they have live musicians too?
Some do, which would be fun! Just know if you do ever go drinks are cheaper at the bar than the tables
