I always kick off my stay with a stroll across the Seine to Boulevard Saint Germain where I sit down and order a nice, cold glass of Champagne at Café de Flore. The café was–and still is–the watering hole of literary types, but it attracts everyone: elegant locals, fashion folk, and tourists. People watching from the terrace is a local pastime.
Don’t let the prices scare you away (a Perrier costs about $7 and a club sandwich will set you back about $25). An afternoon on the terrace offers some of the best entertainment Paris has to offer.
