With a large family, eating out can seem like an impossibility. But, in today's economy, more and more restaurants are realizing the valuing of catering to families with kids. Lots of restaurants now offer Kids Eat Free nights (or close to it...some are actually Kids Eat for 99 cents, but it's still a killer deal). In attempting to make a great list for you, I stumbled upon a great site that will give you a list specific to your state. Check it out and enjoy meals out with your kids!
I saw they are also adding a site called mykidsgofree.com. It looks like a great resource for vacation and fun ideas, though it hasn't filled all the states yet. If you're in one of the lucky states that are listed, you may also get some great activity ideas for free, too!
