Is there a freeware mac program I can use to build a menu for a restaurant?

Well, I am a Mac user myself, and it usually happens to be igned to create brochures and such things (not restaurant menus especially) and admittedly all my work is veeery nicely done through PAGES. Have you tried working there? I suppose you expected something like a template, but Pages would have some for such cases too! Even if not so, try working on a blank Pages doent. If you are a little creative, the results will be more than fine.
