You can do this:

    <a href="#something"><button>menu</button></a>

Or maybe:

    <form action="#something"><button type="submit">menu</button></form>

Not sure either of those options are better than the original post though :)

The latter would probably work, but the first is invalid HTML – you can't nest interactive elements. Will browsers allow it? Yes. But it's still invalid per the spec.
