Having read so many of your wonderful reviews, I'm not hear to just blindly ask for "where should we eat in Paris?".
Instead, my spouse and I would like to eat at some of the following restaurants, between December 22 and January 2, and want to know when we should make reservations, or if it is already too late for some of them. Thanks. Also, if you have any general advice about the period (especially December 24, 25, 26), please feel free to share as well. I assume most things will be closed for Christmas.
