In the words of my 6.5 y.o., who insisted on a five star rating, "I like using it because I like feeding the people food that I cook. Sometimes they spit it out and that is funny. It is a fun game."
The sound effects--preparing, cooking, eating-- are entertaining. It also requires kids to do things in a certain sequence while still allowing them some creativity and silliness. In some cases, it provides an unexpected (and silly) outcome requiring them to try it a new way.
We have been enjoying this app for over a year, now.
