One of the most expensive real estates districts in Paris, the Boulevard Saint Germain is a great place to shop, dine, drink, practice French, and write a timeless story of an American abroad. It worked for Maugham, Hemingway and Fitzgerald. Walk the footsteps of these Expats: you can people watch at Café Mabillon, have a glass of Pernod at Café Flore or write a classic tale of post World War angst and detachment at Café Deux Magots. Pay for the trip.
