Centering an Unordered List

Hello,

I know what you’re thinking, this has been answered previously. I’ve looked at those answers and tried implementing the code but it hasn’t worked for my situation.

I have a nav bar (the dark grey one) at https://wp.vacau.com/ that I’m trying to center up.
That’s all I’m trying to do, I’ve tried using text-align: center; and various other attributes.

Any help would be appreciated!
Thanks,
