I wrote a post earlier, Lets move  a string member into the Menu class.  The make the menu in restaurantInfo a list of Menus. 

Also add a class called CustomerRequest and there should be a list of those in here as well.  This class would represent a physical request from a customer like "Water Refill".  It could just contain a String for description and User member.

I can do this if you want no problem just let me know
