I'm a fan of Chick-fl-a. They're good (better than McDonalds), cheap, and friendly. Be sure to tell them 'thank you' at the end of an order. I'm willing to bet they'll answer with a friendly, "My pleasure". (Try to see what happens at the McDonalds up the street if you try this!)
If you dine inside at this location, they have an enclosed play area for the kids.
If you come for lunch at this location come before 11:00am or after 1:00pm -- ESPECIALLY if you plan on using the drive through. They have quite a congestion problem in the drive-through at lunch.
