I have a hard time avoiding french onion soup or any bits of 'offal', particularly if I don't know how to make it or have never had it cooked that way before. Often, I find these things so irresistible that it doesn't matter if the resulting order makes no logical sense. Pigs tail starter and chicken liver main? French Onion soup and jambalaya?
What about you eaters? Is there something you must try if you see it on a menu?
