Mimi's in the Marigny
You're starving. It's midnight. Move your party to this divey gem that never seems to close. Downstairs looks like a regular old bar, but do not underestimate the late-night tapas menu (yes, tapas). Head upstairs and order patatas bravas, mushroom manchego toast, goat cheese croquettas, and other delicious snacks to soak up the alcohol.
