Maybe once or twice a month for an actual meal, and about once a week for coffee and a pastry or something light in the morning. I try to avoid full service sit down places on a regular basis, which really helps my wallet out. The biggest shift for me was to have a small supply of easy meals for when I got home, that way if I was out, I could have a small snack that I usually carried, and that would tide me over until I got home. It's a bit of a change in perspective, but getting rid of the thought of 'I need food right NOW' has helped immensely. Granted, there's still times I need some food right then and there, but it's few and far between on most days.
