Yes, you can order what ever you would like for the kids.
What I ended up doing after a few days is if there was another entree that I wanted to try (especially a pasta dish), our server would bring me a side order (a smaller bowl or plate) of the dish I wanted to try. We had to laugh because most nights we hardly had room on the table since we tried EVERYTHING. Our servers, Gerish and Viviane would often wait for us to make room and bring another dish when we empty a plate/bowl. We sure had fun eating.
