Keeping with the times, a Zagnut would be a good choice, protein but no chocolate (Sparky, don’t go there). For that, I’m thinking a plain old fashion Hersey’s bar really can’t be beat. Or would Illya bring a love of Cadbury with him from England? Would they be likely to want something more complex like a Milky Way or Snickers or just plain chocolate?
What say you, cousins?
