Eat this, Not that is a series of dieting books that tells how to make good choices at nationwide fast food and restaurants. Its a book that I now carry around with me, and look up guidance by restaurant name. What I wish I had was an app that had all that information in it, plus had a mapping search feature that knew all the good food choices by cross referencing by resturant name. Then it would plot smart food choices on a map near me based upon settings that are right for me. Furthermore it could have a calorie, fat, carb budget that it keeps track of by you telling it which menu choice you actually had. By dinner time you may be limited to a very small calorie budget and that would affect what it showed.
