We came upon this ravishingly pretty flower shop on the way home tonight. It's called Au Nom de la Rose (www.aunomdelarose.fr). Isn't that gorgeous "ball" of roses insanely romantic? Just outside and inside the door of the little shop (it was a little breezy this afternoon) the floor was littered with rose petals in all the colours you see here.
If you had to live the rest of your life on this one block of Rue de Rivoli, you could be happy. After you'd chosen a bouquet of utterly gorgeous roses, you could then shop next door at the boulangerie and patisserie. Steps away are a wine store and a cheese store. A butcher's too, I think. Definitely a little area to go back and check.
