Cut out the $35 - $70/day eating out. You can cook a few things on weekends that you can just heat up. A lasagna, a roast with potatoes and carrots. I am assuming you can all eat leftovers. Probably healthier for you too. I can't imagine eating out every day could ever be considered healthy.....And your setting your kids up to think that it is normal to never eat an actual meal at home - so they will want to eat like that for the rest of their lives, since they probably don't know how to cook.

Everything else in your budget is chump change compared to the $1,000 - $2100 you spend at restaurants each month.
