Considered one of the best TZ episodes for some reason. It's a good episode with a ton of flaws. Mainly being if your overall goal is to come to earth to trick people into willingly coming back to your home planet so that you can eat them there... why the holy fuck bring the goddamn cook book to earth at all? You especially wouldn't just leave it behind after a meeting for the people to find and possibly translate. These are supposed to be superior creatures.
