Spending one evening in Paris in November before flying back to US (after visiting our son studying in Aix). Hotel is in the Place des Vosges. Any dinner suggestions for a restaurant in walking distance that would make the evening memorable? (We like to walk, so it doesn't have to be that close.) I know L'Ambroisie is right nearby, but I don't know if I want to completely break the bank on this meal. Any other thoughts? Thanks!
