It would normally be this – .epik-gray .genesis-nav-menu a but it looks like you added some code that overrides it – .site-header .widget-area a and .epik-gray .head-wrap a on line 3123. So you could remove and replace that with – .site-header .epik-gray .genesis-nav-menu a if you want to make a custom section for it……and then add in your font-family, color, size, etc
