We got the ceasar salad at CR in April this year and added on the scallops and there was no extra charge. The server pointed this out while taking our order. My husband got it again on our second visit (same trip) and again there was no extra charge. Most servers will tell you up front what is extra. HOWEVER, things seem to change at WDW very quickly and though it was only 2 months since that visit, you should still check, but the scallops really did make the ceasar salad great, afterwards I could not eat my entree as I was full, because the bread is great too. (Too bad the entree wasn't great, at least what I ate of it.)
