My lunch nowadays is at home and always with homemade and healthy food, nothing pre-made or bought but when I worked as a salesman I had to eat in a square, or places like that if I didn't want to be paying and go to a restaurant, as I was out all day. I would take my own food, homemade... the only thing is that I would eat it cold, of course, but I knew what I was eating.

But I've seen my colleagues eat very badly, fast food, poor quality food... or not eat at all. And you have to take care of that detail to have a very good health.
