I eat a lot of different foods, but I can't think of anything I've had that is out of my comfort zone. Haggis-ok, chead cheese-ok, tripe-ok, tendon-ok, fish eyes-ok, fish skin-ok.
I eat pretty much every kind of regular animal part, fish part, fungus, root, etc.-- except duck feet. Can't get past the webbed feet.
I don't like game meats (including farm-raised versions of the same animal), but that's because of the taste.
