Restaurant Food Menu CMS

How are you dear, I have a new project which is to create CMS for Restaurant Food Menu, they want to update their menu only so they want CMS for menu here is the link of their new website which I have designed [login to view URL] & they want the menus which will be like this [login to view URL] & [login to view URL] so now these are in pdf format they don't want pdf any more it will show on website which they can update so i was thinking to give a drop down menu style for this so when someone click on any of their menu will show the entire menu like when someone click on "STARTERS" it will show at the bottom of "STARTERS". "1 BBQ Spare Ribs ............. £5.00 2 Chiew Yim Spare Ribs (s)£5.00 in spiced salt, garlic & fresh cut chilli 3 Sesame Prawns on Toast£5.00....." This will go for all menus. Also the section for "Special" on the left side will be able to update from admin. They just need a simple CMS to update these two things. We need to finish this by Sunday. Waiting for authentic response. Thanks, Danil Dilawar
