I'm shocked that you've been charged more for gluten free food. I'll likely always get some type of dining plan just because that way I don't need to worry how our customized meals are rung into the computers, so I really don't know how things are charged. All I know is that cashiers always seem to press a button for a meal that seems to be the closest equivalent to what I get. For example, if they use a gluten free bun they'd choose the hamburger. At Pop's food court, the chef made me a gluten free pasta w/veggies & shrimp stir fry (I had to get this a second time as it was so amazing

) and it was rung in as a pasta and chicken alfredo dish since that was the closest thing on the regular menu. My daughter's mac & cheese with chicken strips (gluten & dairy free and delicious

) was rung in I think also as the pasta and chicken alfredo (it's pasta with chicken). Again, I've always been on a dining plan, but there's never been a premium charged for our meals.
