Tachihara definitely means human food when he talks about eating... It's more than his preference, since it's what he's used to as well. Jouno has never quite managed to change that in him, even if he has tried. He smiles. "Of course they'll have food. Pretty good food, too."

And then, since he does know Jouno doesn't eat at cafes very often: "I can recommend something I think you'll like, if you want."
