Kinda fun...
It was fun for a bit, but a little repetitive. Making your own dish was a neat touch and I liked that, but only having 4 or 5 things to make, and many of them being more or less the same was dull i.e. chicken wings/fries, salad/ice cream.
This game would be more enjoyable with some greater variety in the dishes, or perhaps you could do different jobs each day to keep it fresh. Like being the waiter, or chopping produce. Or perhaps gaining experience to open up dishes and jobs to add content could be fun.
