Thanks so much for the tips, everyone!
They are all very much appreciated, though yours especially, Rahsaan, as it is near where I will be staying and I don't think I could have ever found it on my own.
Unfortunately, I will be nowhere near Montmartre this time around, Sam (but perhaps in the future); and Caves Augé certainly appears formidable, as the French themselves like to say. I may well make it over there as well, Mark.
Again, many thanks,
