Have you been to a restaurant where the menus are sticky and dirty, or the covers cracked and broken? If this is your restaurant maybe it's time to update your menu. Today, everything is about the "big-wow-factor" - that must include all of your graphics, especially the menu. Don't give your customer any excuse to be critical. Provide them excellence in all areas. Graphics are such a big part of your brand. Take time to review all of your graphic materials including your web site.
And when you do update your graphics think about updating your menu items and prices as well, plus refresh your Web Site. Stay current, offer something new, and watch the customers come back for more.
