How can I make space between two buttons in same div?

What is the best way to horizontally space Bootstrap buttons?

At the moment the buttons are touching:

<div class="btn-group">
    <button class="btn btn-inverse dropdown-toggle" data-toggle="dropdown">
        <i class="icon-in-button"></i>  
        Add to list
        <span class="caret"/>
    </button>
    <ul class="dropdown-menu">
        <li>
            <a href="#">here</a>
        </li>
        <li>
            <a href="#">new</a>
        </li>
    </ul>
    <button class="btn btn-info">
        <i class="icon-in-button"></i>  
        more
    </button>
</div>
