Chez Alain Miam Miam

Alain Roussel, known to the entire 3e as 'Alain the Crêpe', opened his stall inside Marché des Enfants Rouges in 2005 and has spent twenty years assembling exactly two things: galettes and the sandwich that has become a Paris food-tourism landmark. A baguette toasted on a panini press, organic Comté, mortadella, lettuce, herb pesto, mushroom spread, all built to order by Alain himself, hands moving while he chats with the queue. Vegetarian options work. The line, frequently 30 minutes deep on weekends, is part of the experience; locals walk the sandwich to nearby Square du Temple-Elie Wiesel and eat on a bench. There's a sit-down annexe on rue Charlot if you'd rather skip the queue.
