"Makunouchi" is a kind of bentou, served during Kabuki in the olden days. It either got its name from the lunch the audience would eat during intermission, or perhaps from the lunch actors would eat during this time (seems plausible since the actors are also "behind the curtain", which is actually the literal translation of that phrase).
