Cooking simulator! Be a professional Chef! Cook whatever you like!
Heyy dude, Great code! But just one suggestion, maybe instead of showing the food in list form, you can make it so that the list of foods is indexed like so:
 Burger  Pizza  Roasted Fish
So that if a user wants to sell an item, he doesnt have to type in the whole name of the item letter by letter, and can just type "2" if he wants to sell "Pizza", hope you understood and make that change.
:D Good luck for your future projects!!
