Ladurée, founded in 1862, is a French institution and a great place to stock up on some delicious chocolates, pastries, and macaroons in flavors such as violet, cassis, amaretto, salty caramel, tea, and bitter lime, to name just a few. They sell more than 800 macaroons a day, upwards of 60,000 hazelnut croissants per year, and use approximately 30 tons of chocolate a year -- just to give you an idea of how popular they are. Stop in for a taste in the tearoom and bring some of your faves home -- if they make it that far, they'll love you for it. Métro: Odéon.
