m0ln4r on "Menu items centered, except for one"

Hi everyone!
This is a site for my friend and I have one little problem. Actually two.
vinogradništvo-mlinarič.si
I'm using the Twenty Eleven Theme.

So I centered the menu items with:

#access a {
	text-align: center;
	color: #eee;
	display: block;
	line-height: 3.333em;
	padding: 0 30px;
	width: 60px;
	text-decoration: none;

My problem:
As you hover over the "Predstavitev" you can see that it is not centered, but the other items are. Why?

Thank u all in advance! Oh and i'm a CSS beginner so please keep it simple.
