Dinner menu changes to something you just don't like, do you eat it even if it grosses you out?

Do you “man up” and stomach it and chow down or bow out before you puke? You get invited to a dinner where you thought the main course was rib eye steak, but when you get there you find out the menu was changed and are told letters were sent out stating the change but you never got one. The main course now is chitlins (aka chitterlings) and haggis (bi–racial couple) because out of town family will be attending and they are family favorites.
