Food Delivery Website

Am thinking of building an online restaurant food delivery website for my town, where users can create an account with their address and start ordering from restaurants in their area. Every restaurant will also have a login where can add menu items with rates, delivery timings, minimum amount, and special promotions announcements. I would like also to have an orders que, showing current orders on the homepage of the site (something like the one in w w w . 6 a l a b a t. c o m) There will be no payments processing, users will pay cash on delivery. The web admin or the restaurant account owner will be able to release the order if made to his restaurant, and the user who ordered will then be able to review the restaurant, and the item ordered. User should be able to see their orders history and repeat any previous order with a click of a button. An interface should be built to look nicer than just filling a quantity input box next to each item on the menu..am thinking of a plus button next to each item and have the result displayed live on a side panel
