Improve the line height of menu items

Hi,

Can you tell me which CSS I need to improve the menu items?
It's about the top menu, item "Over ons", see private area for the website. If you click on it, you see that all rows have the vertically spaces.

For the visitor, I think it will be more readable that the rows of a single menu item have a smaller line height. And the line height between menu items should be a little more.

Can you help to improve the layout?
If you have any other suggestions that would be even be greater :-)

Thanks Henk.
