If you asked me what my favorite thing I did in Paris was, I would definitely reply "Walking around and eating!"
With so many cute cafes and dessert shops, you can achieve both of these joys simultaneously. When I was wandering around the classy Ile de St Louis, I saw this little chocolate and caramel tart in a window and had to stop and by it. I'm not sure which was more cute - the dessert or the street I bought it on - but I DO know that it ranked in the Top 5 desserts of my entire life. Mmmmmmm!
