The reason that a state capital city usually has a "lunch economy" is because of the lobbyists; they buy lunches for legislators and for bureaucrats, whose support they wish to have for the causes they are being paid to push. It's also fairly common for politically-appointed department heads and/or attorneys to buy lunches or evening meals for staff and have them delivered, if there is a big deadline project that needs to get done ASAP.
Personally, the answer is no; I'm not well-paid enough to afford to eat out on days when I work in the office, nor do I have the time, because my office is in suburbia, and it's the equivalent of a 6-block round-trip walk to my parking area from my office. Our standard lunch break (unless the boss is treating for some reason) is 30 minutes. I refuse to use 3rd-party delivery services just on principle; around here they tend to cost more than the meal itself.
