Within the fast-food genre:
Chik-fil-A has good chicken certainly. We probably should avoid the political issues.
A fresh Whopper is a great burger.
But...I have to mention this, since my wife has lost 90+ lbs, and I've lost 30 lbs over the last year: we pretty much avoid fast food entirely. Erica loves Chik-fil-a (especially their BBQ sauce) but we go there a LOT less than we used to because of the diet. We now pack sandwiches to eat at rest areas, for example.
I frequently stop at Subway after my workouts and get a 6" roast beef on wheat, no cheese, with lettuce, tomatoes, pickles, black olives, and green peppers for dinner. Roughly 300 calories plus the veggies. Then I'll have a small peanut butter cup or two for dessert.
