Event Manager listing [Increase text size]

Hi there,

And thanks for your time. Question:

To all the good folks using this plugin [Event Manager: http://wp-events-plugin.com], this maybe straight forward and simple, to what folder or file do we go to increase the text and make things wider on the events listing and calendar?

We have looked at: events_manager.css, event-list-default.html, events-list.php etc but no joy.. Below is the direct link:

Thanks for your assistance in advance.
