There are certain items that aren’t included but they will have it marked next to them that there is a surcharge if using the dining plan. For example there is a $125 wagyu strip loin at Yachtsman that requires a surcharge, but if you look on the online menu it says this right in the description.
Also, certain alcoholic drinks like wine flights aren’t included, but most are.
I believe the threshold for whether a signature entree has a surcharge or not is $75, but I could be totally wrong. I know DD was able to order the $75 rib-eye at Cali Grill two weeks ago.
