I think a lot of it has to dot with this incorrect assumption about restaurants: expensive=healthy (think some farm to table hipster joint in your local hip urban area) and that conversely inexpensive=unhealthy (think Chilis or even McDonalds). When in reality you can eat healthy  6504   at a cheap restaurant or eat unhealthy at an expensive one... but that brings us back to the whole fact that they have to put effort into it and think about again, so I guess apples are apples.
