You really are doing your research before you arrive aren't you!
Chick fil A is allegedly 'healthy' fast food (true sense of the word, drive through, paper bag etc). It takes a bit of getting used to but it is OK.
Restaurant Chains - on the border (mexican), Chili's (american), TGI's are all family friendly and favourites of ours (or is that favorites). Max and Erma's - similar to above.
Cheesecake factory is expensive but nice for a treat. Just go for coffee and cheesecake or you'll be too full to appreciate the main event!
Panera Bread makes the nicest bagels and other bakery goods (it could be your saviour when it comes to avoiding overly sweet supermarket bread - you were warned). It is my favourite breakfast spot.
Macaroni grill - nice italian chain. Maggianos - more upscale italian chain.
Jason's Deli - sandwiches / salad / soups in a hurry.
Can't think of others at the moment, will write more when I think. Healthy could be an issue though...just remember to get a box for what you don't eat and have the rest the next day.
