The word bouillon refers to the workers’ restaurants, found all over Paris back in the 19th century. The idea was to offer good food at modest prices, a concept that still speaks to working Parisians some 100 years later, if the line out the door of this brand-new, 300-seat joint is any indication. You come here to tuck into classics like leeks in vinaigrette, beef bourguignon, and chocolate eclairs at prices so low (think 1.90€ for a starter, 10€ for a main, and less than 4€ for dessert), you wonder how they make a profit. The menu covers a wide variety of traditional dishes like steak with fries or rum baba. Service is fast and furious, but it’s all part of the atmosphere, which is something that belongs to another time and place. You cannot make a reservation, so be prepared to wait.
