I do think when I've seen the French eating duck with mustard it's been at simple dining places rather than places serving elaborate dishes. So maybe there are some fruit duck dishes to be had in France.

I just don't care for any type of sweetness with meat. We went out to dinner with friends and afterwards the friends joined us at home for cake and ice cream. I drank a glass of wine as I just couldn't stand the idea of cake. I just don't love sweet things all the time. There are exceptions to that rule, though!
