Online Order system for a restaurant menu

SYSTEM BASIC
Written in php/ajax?
all information stored in MySQL database
Language support for admin & public menus
System uses templates.

Orders are delivered to a specific email address.  Is there any other options?  (Or is it possible to have auto printing of each order?)

Set tax % (has a default but allow by location), if large delivery area, they could deliver to multiple counties or tax zones
Set delivery fee (possible Multiple fee based on mileage from zip code db (which I have if needed))
Coupons: they can be a %off, or $ amount of money, or a select item at set price Like large pizza $5.00 ** all coupons should have a date range, but if no end date it stays valid.  At time of entering start date should default to today's date.
