Well that's why they have soup of the day, hors d'oeuvre are also often Items that use up fresh food that require using up, but this does not make it bad food or lower quality, it really depends on the chefs skill, when you run a kitchen that uses fresh produce it only has a very limited shelf life, so if it's a good restaurant with a quality chef the you should be getting great value for money and good food if you eat the special. If its a poor restaurant then don't eat there period.
