I just checked
www.dwlz.com - tons of restaurants listed, but no Checkers. I don't think I've ever been to Checkers, so I am assuming the chicken is fried, not grilled.
Here is my guess: 17.5
How'd I get there? Wendy's. A spicy chicken filet (fried) is 11.5 points and a kids size fries is 6 points.
When I eat out it is usually at a mom-and-pop or local restaurant, so I find something similar at a similar style restaurant to estimate points.
