Yeah, Napoleon. Personally, I'd go with all conquerors-
Napoleon, Genghis Khan, and Alexander the Great.
Napoleon: we'd have some really exquisite food and he'd open up to me about his relationship with Josephine and what a mess it is. Then we'd talk military strategy.
Genghis Khan: we'd have big use cuts of meat and eat it right off the bone accompanied with alcohol made by yak's milk. Then he'd bring out his exotic women from everywhere.
Alexander the Great: we'd talk about the things Aristotle taught him, and also about how kick ass Macedonia is.
