FWIW, Don’t EVER ask a policeman unless you are one yourself and are in uniform. You’ll get any place that offers free food, not necessarily good food.[:D]
In Hannibel Mo. years ago we asked a mailman and the req was so good, I’ve always searched out a postal worker for their choices. If its a real small town, I’ve had good luck with diners near city government too.
As far as the given poll, something I can’t get at home is always my first choice unless I’m in Q country.
