Trivia: Carrie is carrying a small bunch of violets in this Parisian montage. What is interesting is that in France, traditionally, violets are the flowers that the husband gives his wife when he has disappointed her, or they have had a fight. Symbolically, the violets that Carrie bought for herself represent that she is continually disappointed by Aleksandr.
Trivia: The music during the Carrie montage in Paris was actually written by Mikhail Baryshnikov. It's called 'Carrie's Theme', and is the same music that Aleksandr played to Carrie on his piano in 'The Ick Factor' episode. The show had the music scored by an orchestra, and used it during these scenes. Michael Patrick King wrote the entire montage, with this music in mind.
Trivia: The coffee shop has always been a set, on a sound stage. But in this scene, the girls are leaving the coffee shop to walk out on the street. Sex And The City had to build a real coffee shop exterior, so that the girls could walk out into the real world.
