Hi @X-DREAM 

This is Mike from Omega

If you could not find the base.css, you can add the code to core.css or main-nav.css.

I check and see these files on your store.

Hope my answer will help you

Thanks Mike, can you please also check the blew code if this is the right code.

summary.header__menu-item.list-menu__item.link.focus-inset {
font-size: 20px !important;
}
a.header__menu-item.header__menu-item.list-menu__item.link.link--text.focus-inset {
font-size: 20px !important;
}

Hi @X-DREAM 

Check this one. The current size of the font is .9rem

From your Shopify admin dashboard, click on "Online Store" and then "Themes".

Find the theme that you want to edit and click on "Actions" and then "Edit code".

In the "Assets" folder, click on "main-nav.css or core.css" file, depending on which file your theme uses to store its CSS styles. At the bottom of the file, add the following CSS code:

nav.\#main-nav a {
    font-size: 20px !important;
}

 And Save. 

Result:
