minimatica theme; sidebar menu font increase

Hello everyone,

I need a bit of help tweaking the font of the sidebar menu widget on my site Lazy Star Horse Company

I would like the font of the sidebar nav menu to be the same as the h2 text found in the rest of the sidebar headings. I’ve spent most of the morning trying to tweak parts of the stylesheet to no avail. Can someone point me in the right direction? Thanks so much!
