I've about decided that the best approach is to find one or two items on the menu of any of these places...and then order that when you are hungry. Avoid getting more items or experimenting too much with what else is on the menu.
Incidentally, there is a great variance between the different fast food restaurants when it comes to the calorie counts, carbs, etc. on their standard sandwiches. Taste is one thing, but if you're watching your weight or some ingredient, you'd be surprised at how much a burger from one place can differ from the burger at the competing drive-in. They all publish their statistics somewhere.
And finally, quality control matters. To me, at least. Some places have tasty food but you can never count on it being the same two times in a row. I have basically decided to omit these from my consideration even if "when they're good, they're good."
