Louvard’s claim to fame is the crookie, the viral croissant-cookie hybrid that’s been replicated by every corner bakery from Paris to Phoenix. But Louvard’s is the GOAT regardless, thanks to their exquisite butter croissants, which are skinnier than many of their competitors and give you the perfect crispy bite from beginning to end. They’re stuffed with cookie dough and just barely rebaked, and the result is a gut bomb that's impossible to finish without being within stumbling distance from a sofa—not that that should stop you from trying. But locals return here again and again for their other viennoiseries, like the apple chausson sprinkled with raw cane sugar and filled with applesauce, or the fruity chocolate éclair—probably Paris’ best. It’s tempting to enjoy your treats at a table in the adjoining dining room. But be warned: There’s a hefty markup to soak up these classic Parisian café vibes.
