The Bonnard expo at the musee d'Orsay is very good, if you like his style. As you may know, they have a nice full lunch in a gorgeous dining room there.
Another thought is the Jacquemart, which currently has an expo from a private collection I have not seem. They too have a pleasant, full service lunch.
I strongly urge getting tickets in advance for either, and especially for the d'Orsay which is packed on Tuesdays since the Louvre is closed.
