Mars 2112 was super big on duck meat.  There was duck pasta, duck pizza, duck everything.  I think it was supposed to make food taste slightly off-from-normal, and thus feel more otherworldly?  Also, the entire menu was expensive (because the simulator ride and the whole *gestures broadly* decor-based experience was free), so if someone gets huffy you can be all like YEAH WELL DUCKS ARE PRIMO, OKAY
