Joomla! Template Diner PT - Item Support

Very nice theme. But there is a problem.
Main Menu >>> submenu. Dark background with dark ink.
What do I do? How can I change.
Background brighter or lighter font. If background light, then there is a problem with links in the content.
It is better if the background of sub-menu is brighter.

What do I do?

kind regards
