I'm not sure about the sharing charge. I don't see it on their published menu anymore and I don't see it referenced on their website, so that leads me to believe they have done away with it.
I know they had it in the past and we were never charged. Not sure if that was because we had kids, or maybe because we ordered sides and appetizers. Or maybe they never really enforced it?
This is a recent sample of the children's menu as posted by Uncleromulus:
Chicken Noodle Soup-$6.95
8% Chicken Breast-$11.95
Cheesburger-8.95
Mashed Potatoes-$4.95
Mac&Cheese-$4.95
A few years back they also expanded their sides and appetizer offerings, and our kids have enjoyed some of those, such as:
Shrimp Cocktail $14.95
BBQ Shrimp stuffed with Basil $14.95
Jumbo Lump Crab Cake $16.95
Crab Macaroni and Cheese (A BIG hit) $12.95
My son (13) orders off the entree menu now, but my daughter (6) still goes with the sides/appetizers. Here's a link to the current full menu

The desserts are great also.
