There are always lines outside Bouillon’s two locations, and that’s because from noon to midnight every single day, the kitchens pump out classic French dishes at super low prices (€20 can get you exactly eight orders of oeuf mayo, should that be the direction you want to take your day). Swing by the one in Republique after walking around the Marais or the Pigalle outpost if you're in Montmartre. Order the onion soup, snails with parsley butter, and the quarter roast chicken with fries as you map out which wine bar you’ll be hitting up for apéro.
