What wld you do in Paris - long weekend

[Folicky]

Going to Paris in a few weeks Fri - Mon, will be done and with the main purpose of the trip by the end of the Friday. What could we (me (50yo), 12yo and Male partner) do for the rest of the weekend? We’re into music but not dance or techno, like some museum/ buildings/ cultural activity but not too much; not huge foodies but like eating out for dinner. Been to Paris before so already done Louvre, Notre Dam, Shakespeare & Co, Jim Morrison etc). Any good music venues, relaxed nice dining experiences or other slightly off the beaten track-type cultural experiences we could go to?

The Catacombs are really interesting, my teens really enjoyed that. Maybe a boat trip. Something I also love is Napoleons apartments in the Louvre and there is a great cafe at the back of the Louvre (needs to be booked)

We also did a cheese tasting which was fab, booked it on Viator. You could also get a boat trip, a good area for food is the Latin Quarter near Notre Dame and also Montmartre in the section behind the Moulin Rouge. LOVE Paris.

Sorry said boat trip twice.
