In terms of restaurants, I almost never eat out. I do get a lot of fast food when I'm in school due to my schedule. I'm there at least 12+ hours and my house is a good half hour drive on a good day. I also have a big backpack and carrying 2 meals is too much bulk, imo.
I don't too much. Sometimes they bring food in at work (CFA, Krispy Kreme, and pizza are pretty common) and it'll be in the break room. Fast food is pretty overrated, and the food is normally barely eatable.
I rarely eat out. I prefer making my own meals and trying new recipes. Sure, I do have the occasional take out here and then but its probably say once in two weeks.
About 4 days a week,I eat out for lunch but more often, it is in the office canteen. I sometimes bring my lunch to work but only when I like the leftover from the previous night's dinner. The expense for eating out is already part of my daily budget. But during weekends, we seldom eat out because we enjoy cooking special dishes like seafood and casserole dishes.
