Change menu padding for long list of items

Great theme you put together, and I am having so much fun using it. However, I have long lists of categories on my menu. Look at http://www.fireinvestigatordirectory.com There is too much top and bottom padding on each menu item, which causes the drop down lost to go way down the page. Fine for people with large monitors, but not so good on smaller monitors. I searched your forum, and could not find a help article on how to change it. Where do I change the top and bottom padding on each menu item, under for example, Structure Fires, Midwest, and the States that are listed, so that the list will be shorter. Your stock settings are terrific for short lists of menu items, but for me I need to make the list shorter in length, and still keep the same amount of items in my menu. I tried the Mega Menu format, and don’t like it.

Thanks in advance, you’re doing an awesome job.
