Founded in 1862, Ladurée oozes period atmosphere—even at the big Champs-Élysées branch (No. 75)—but nothing beats the original tearoom on Rue Royale, with its pint-size tables and frescoed ceiling. Ladurée claims a familial link to the invention of the macaron, and appropriately, there's a fabulous selection of these lighter-than-air cookies. Classic flavors include pistachio, salted caramel, and coffee; others, like violet–black currant, chestnut, and lime basil, are available seasonally. When you've worked your way through the macaron menu, try a cup of the famously rich hot chocolate with a flaky mille-feuille. Ladurée’s stylish boxes alone are worth the purchase; filled with sweet treats, they make memorable gifts.
