Du Pain et Des Idées is a must-visit Paris boulangerie in the 10eme. They have a wide variety of exceptional viennoiserie, their escargot are world-famous and definitely live up to the hype. 

Saturne is an exceptional mid to high-end restaurant that serves a range of superb seasonal dishes. Their set menu is the way to go, but if you're in the mood for something a bit more extensive - go with the full tasting menu.

Bistrot Paul Bert is a reasonably priced, high-quality classic French restaurant with friendly service and a charming setting. You'll find it packed with both locals and tourists. Make sure to order the Soufflé au Grand Marnier
