I do a lot of work in New York City, which makes for a very expensive lunch. Typically the van is parked five or six blocks away, and it gets too hot in the summer to really bring anything with me, and too cold in the winter to want to have cold soup or a frozen sandwich, really makes it hard to want to bring lunch. If I can get lunch for under $10/day I am happy, if I am feeling adventuress I will go to one of the street carts for some "chicken" & rice, usually about $6 with a soda. If my PM comes out then lunch is never under $15, and I see him at least once a week. If I brought lunch I can't even imagine how much I would save.
