Wordpress: Any way to selectively control caching for content areas on a page?

In a Wordpress site, is there a way to allow site-wide caching, but force
certain areas of a page to reload on each visit?

For example, if  on a specific page there is a huge navigational menu that
never changes, a map that rarely changes, and hours of operation which
change frequently (as often as holidays), is there a way to force only the
hours of operation to reload when a person revisits the page?
