Using custom fields to create a restaurant menu?

Hi all,

I would like to create a menu on my site where I can input the item title, item description and price in the admin area and then these values be added properly to the appropriate areas of the menu page of the site.

The menu structure would be something like this:

<section class="menu_item">
<h2>Menu item number 1</h2>
<p>Item description<span>£2.50</span></p>
</section>

Ideally I would like to create an area in the admin area called menus where I can create a new menu called Lunch Menu and then add a new menu item which would consist of custom fields/placeholders?

If someone could explain how this can be achieved then that would be great, Im not entirely up to speed on what can be achieved using wordpress so the more advice and info I get then the better.

Thanks
Kyle
