Vertical Menu Display

Hey guys, I'm having trouble with creating a vertical menu on my WordPress homepage site. The menu is currently horizontal across the top of the page. I would like it to be vertical, Sort of like a table, but with the menu options centered and the font bigger. I will provide the css code for the website in an attachment. The url of the site is importtheater.com if you would like to look at the current menu. Thanks.
