Moving content above navigation menus using CSS will generally help. Google parses HTML to build description snippets (as opposed to just stripping away HTML and looking at what's left) when it doesn't find a META description tag and it does a multi-phased scan from top to bottom, using HTML elements like H, NOSCRIPT, HR, DIV, TABLE, P, ALT and other stuff as markers. Little things like H1 text wrapped in HREF can make Google pick up your navigation text instead of your page copy.
