There's a delightful build a bowl station on the pool deck by the Magic - we found it on our first day and I went back nearly every day of our TA cruise. Here is a terrible picture but the options do change often. I believe rice is often offered as a base (maybe always, I'm not sure) but you can also do salads, quinoa, and sometimes there are noodles.
And if they show "Princess and the Frog" ask for frog...no I'm not going there...yikes!
So if they show Coco should we ask for a tortilla bowl?
