Paris recommendations pls

Because I have left planning this trip awfully late: anyone particularly want to recommend anything in Paris for me to do? Vegetarian food esp. appreciated. I am already planning to take full advantage of the free queue-jump at all the museums and galleries (I particularly want to stare at the Impressionists some more but recommendations for bullshit optionally-ceramic sculpture very much appreciated); A has been Informed that I will be going to visit État Libre d'Orange (so that I can smell some of their more horrifying perfumes without having to buy them); and depending on the weather I intend A Stroll Through Some Gardens. Any other requests?
