Here's the information on Chicken Annie's.
Map
Chicken Annie's has 3 locations. They are known as the Original, Annex, and Girard locations. For years I only ate at the Annex location because that's where Grandma and Grandpa took me.
Annex - This is located right at the junction of 69 and 400 highways which makes it very convenient if you'll be traveling north on 69. In my opinion this is the best of the 3 locations. About 30 miles from the campsite.
Original - This is where the Travel Channel filmed the show Food Wars and would be the place to go if you wanted to try out the competition,
Chicken Mary's.

To me this location has the heat up a little too high on the fryers. That's not all bad because they have the best onion rings but the chicken is a little overcooked. About 24 miles from the campsite.
Girard - This one is closest to the state park and has good chicken. The sides I find to be bland here and the onion rings seem undercooked. About 15 miles from the campsite.

Remember that taste is subjective and these are just my opinions on the different locations.
