[We've moved this discussion of healthy food at Chain restaurants from the thread at http://chowhound.chow.com/topics/854014 -- The Chowhound Team ]
Assuming you don't hate chains, I will suggest Saladworks--IF you customize the salads. For example, the Mandarin Chicken salad normally comes with those wretched chow mein noodles on top, but you can ask them to replace those with something healthier (e.g., mushrooms). (Personally, I choose the glazed pecans, probably just as bad, but, oooh, are they tasty!)
When I last checked Saladworks had an interactive nutrition page where you could see what adding each topping did to the calorie count.
