"Bouillon Pigalle is a restaurant of the proletariat. Though it would be more accurate to call it a restaurant of the proletariat of Paris who favor watercress salad, escargots, beef bourguignon, frites, and a menu that is as true to a bistro menu as it can be. Historically, in French restaurant vernacular, a "bouillon" is a restaurant that served bouillon-which is to say good, afforable food, that appealed to the working class. And Bouillon Pigalle is the 2018 version: 300 seats; a festive, bustling vibe; and a crowd willing to wait the better part of an hour for table. No matter. The profiteroles are that good. "
