Adding a custom font to the dropdown menu navigation bar in CSS custom

I'm trying to change the font in the dropdown menu on the navigation bar to a custom font, any idea what code to use in the CSS for this? I can't find anything that works for me on here.. 
Thanks in advance!

.header-nav-item a {
    font-family: 'Eighties';
}
