You should add food and prices too. Obviously you don’t need to implement an actual payment system because it’s for fun, but if it kept track of the money, your kid could charge you 0.50 per drink or something.

That's a nice idea ! Will definetly add it soon.

And for the food, one can already add anything, it's just a text field. A friend of mine only has alcoholic drinks and snacks on his menu page.
