Admin Only Payment Option(s)

Hello, I am trying to get certain payment options to only show for admin users.. I've been searching but haven't been able to find anything for v2.0.. Can anybody help me out?

Is there anything as simple as

if($this->user->isLogged()) {
success
}

or

if($this->user->getUserGroupId($this->user->getId()) == 1) {
success
}

Did you find a solution for this? I'm trying to achieve the same.
