A walk of Champs Elysees is a must in Paris. There are plenty of shops for all to see but boy it will hurt your pocket book.
The original LV store is here. There is also the Cartier shop. But the best part of it all is having tea at Laduree. OMG, the pistache macaroons are to die for! We had rose petal ice cream with assorted macaroons. The vanille and the cafe ones are good too! CAUTION: prepare to pay a hefty price for these sweets.
