If you get a chance to sit at Ladurée you should do it. Usually the people who are sitting are rich and cosmopolitan but don’t let that intimidate you. Be yourself. Also, don’t order whatever that pie thing that’s shown in the picture. It’s like a bad flan. I would recommend sticking to macarons, lattes and Macaron Framboise (not pictured).
My favorite flavors are lemon, raspberry, chocolate and rose.
