Well, DH stops at the gas station or at McD's in the morning and gets a tea and something to eat. He rarely goes to lunch, but if he does, he goes out. (He usually snacks during the day, fruit/veggies or granola/nut bars or popcorn cakes.)
We usually go out to eat on Tuesdays. We have Scouts (yes, we--DS is in Cub Scouts, DH is his den leader and I'm the committee chair) and need to be there by 6:30. We live about an hour away, and DH gets home between 4:30 and 5. So, he changes, we leave and go eat somewhere near the meeting.
We usually order pizza every other week. And do Chinese take out maybe once a month.
So, for the family meals, $150 a month? Unless we go somewhere nicer than Chipotle or Moe's for dinner on Tuesdays... If we go to Bonefish Grill, we can easily spend $60 for the three of us, plus tip. If we do that, then we eat at home the next Tuesday (something simple, like dirty rice or hot dogs and mac n cheese).
DH spends about $5 a day, unless he does lunch. So, another $100-125 a month for him. He was yelled at by the doc because his bad choloestrol (sp?) is high and he's not supposed to eat at fast food. I can buy breakfast stuff and lunch stuff all day long---he forgets to take it.
When we were both working, we ate out a lot. But, I was running a restaurant, so most times, the family would come up to see me, and they ate for free. (Yes, my boss knew, and yes, he was ok with it, as long as I accounted for the food--perk of being the general manager...working 50-80 hours a week has to have some good things come of it...)
