Eating out gets expensive, especially when you have kids.  So we've got a list here of some popular chain restaurants where kids eat FREE at least one day a week.  Here are four of them that offer the best deals.

#1.)  Denny's.  On Tuesday's from 4:00 PM to 10:00 PM, you can get up to two kids' meals for free if you buy one entrée.

#2.)  Red Robin.  Kids eat free on Tuesday nights when you buy one adult entrée.

#3.)  IHOP.  Every day from 4:00 PM to 8:00 PM, you can get one thing from the kids' menu for free as long as you order something else.

#4.)  Applebee's.  On Monday nights, you can get a free kid's meal when you buy one entrée.  And additional kids eat for $1 each.
