There are a few ways to feel instantly classier. You could put a tuxedo jacket on over your pajamas or buy a porcelain gravy boat that costs more than your flight here. Our favorite, though, is ordering a croque monsieur and a bottle of Chablis at 1am, and there’s no better place to do it than L’Express. This Plateau spot is Montreal’s most loved bistro, which means a lot in a city with a majority francophone population and more steak frites than burgers. They’re open until 3am every night (except Sunday when doors close at a more reasonable 2am), so it’s great any time for comforting French classics, and one of the city’s most impressive and affordable wine lists.
