I like to give a shout out to the mobilier rooms because they don't get much love in the guides or discussions.
If you're a fan of the Antiques Roadshow (either the British or the US versions) then you can pretend you're an appraiser and apply all the know-how you've learned from the twins et al in the mobilier/furniture sections -- I like to get the guards to smile by using a small flashlight and a notebook to stoop under the tables and behind the highboys to note the labels and markings, and maybe sketch the ball feet of the chairs so you can get to know the variations of ball-and-claw carving and guess what city a piece was made in.
This is what the google AI says to me about it (ymmv)
