I don't complain if the food is a different recipe from what I expect. Its not like the restaurants share cooking styles. I would complain about the bug though and I'd expect a free meal. I've never been to Denny's, in fact, I've only seen one Denny's in real life while driving past it. We have no Denny's by us. Now the only way I'd ever sue is if I ended up in the hospital from the food, and that's only because I would need them to pay my bill, not to get some rediculous settlement.
